If you get a 429 Too Many Requests error when browsing this site, read on.

You're probably seeing this error because a large number of requests have been made from your IP address over a short period of time. That's probably a lot of requests from you or others who share your IP address (such as your home wi-fi network). Waiting a minute and then retrying should generally work.

If you are an actual human being with a legitimate reason to be browsing the site heavily, first, thank you and sorry about this! We set rate limits to prevent bots, spiders, spammers, and malicious actors from consuming too much of our server's resources so that our server's resources can be devoted to real humans like you. Consider writing to vipulnaik1@gmail.com with your IP address to have the IP address whitelisted. You can get your IP address by [https://www.google.com/search?q=my+ip+address Googling "my IP address"] (scroll down a little bit to where Google includes the IP address in a box). NOTE: If you have both an IPv4 address and an IPv6 address, you should send both; the server supports both IPv4 and IPv6, so either may end up getting used. To check if you have an IPv6 address, try visiting [https://ipv6.google.com/ ipv6.google.com].

If your IP address changes, or you are away from your home network, then you'll get rate-limited again. So if you find yourself getting rate-limited after already having been whitelisted, check if you are on a different IP address than the one for which you requested whitelisting.

Content copied from [[Ref:Ref:Enabling site search autocompletion]]. Images used are specific to this site (Demography).

Site search autocompletion is currently broken by default on this site. This page includes details on how to get it to work, and what's going on.

==What's wrong with site search autocompletion and how to fix it==

===What's wrong===

When you start typing something in the site search bar, you'll see it stuck at "Loading search suggestions" as shown in the screenshot below:

[[File:Site search autocompletion broken.png]]

Note that the actual search is still working -- you just have to hit Enter after typing the search query and it'll go to the search results page. It's the autocompletion before you hit Enter that is broken.

===How to fix it===

To fix it, you need to follow these steps:

* Write to vipulnaik1@gmail.com asking for a login to the site. Please include the following with your request: preferred username, preferred initial password (you can change it after logging in), real name (if you want it entered), email address to use (if you want an actual email address by which you can be contacted), and whether you want edit access as well. You don't need edit access for enabling site search autocompletion.
* Log in to the site. Then go to [[Special:Preferences]]. Go to the Appearance section and switch the Skin from "Vector (2022)" to "Vector legacy (2010)".
* Make sure to hit "Save" at the bottom.
* Now you can reload the page or load a new page.

Site search autocompletion should now work. Here's an example:

[[File:Site search autocompletion working.png]]

==More background==

We've recently upgraded the MediaWiki version of this wiki from 1.35.13 to 1.41.2 (see [[Special:Version]]). The upgrade allows us to migrate the wiki to a more modern operating system version running PHP 8. With the current setup for MediaWiki 1.41.2, we're in this situation:

* The "Vector legacy (2010)" skin has site search autocompletion working, but it doesn't render well on small screens. Specifically, even on small mobile screens, it still shows the left menu, and doesn't properly use the MobileFrontend extension settings.
* The "Vector (2022)" skin doesn't have site search autocompletion working (see screenshots in preceding section) but it does render fine on mobile devices.

It is possible to set only one default skin (that is applicable to all non-logged-in users and is the default for logged-in users who have not configured a skin for themselves). So, the selection of default skin comes down to whether it's more important for casual users to have the mobile experience working or to have site search autocompletion working. Based on a general understanding of user behavior, we believe that having a usable mobile experience is more important for casual users than having site search autocompletion.

However, for power users who are using the site extensively, site search autocompletion may be important. That's why we've written this page giving guidance on how to set up site search autocompletion.

Period fertility in Japan

Vipul: /* Trends in period fertility */

{{country-specific information|information type = period fertility|country = Japan}}

==Data sources==

{{HFD source|country = Japan|country code = JPN|update date = August 8, 2012|download date = December 2, 2013}}

==Trends in period fertility==
<section begin="trends"/>
The fertility history of Japan can be subdivided into the following rough periods. Fertility history prior to 1947 relies on Gapminder, which uses the less reliable UN data, whereas fertility history 1947 onward uses the higher reliability HFD data. However, for the part 1947 onward, the Gapminder and HFD data paint a similar picture, and the only qualitative difference is that the Gapminder data fail to capture the dip in 1966.

{| class="sortable" border="1"
! Time period !! Trend in fertility !! Some numbers !! Details
|-
| 1873-1901 || huge increase || TFR increased from 3.41 to 5.01 ||
|-
| 1901-1906 || rapid decrease || TFR decreased from 5.01 to 4.37 ||
|-
| 1907-1919 || upward jump, followed by modest decrease || TFR jumped up to 5.02 (from 4.37 the previous year), then decreased gradually to 4.77 || The introduction of explicit penalties for women who have abortions in 1907 might explain the jump.
|-
| 1920-1939 || rapid decrease || TFR decreased from 5.35 to 3.8 || The sudden change between 1919 and 1920 may be attributable to the change in data source.
|-
| 1939-1947 || fluctuation || TFR increased from 3.8 to 4.5, but with fluctuations || The war years of 1944 and 1945 were particularly bad for TFR.
|-
| 1947-1957 || huge decrease || CBR decreased from 34.65 to 17.38 TFR decreased from 4.566 to 2.058 || Possibly exacerbated by the legalization of abortion in 1948. Note that the starting point of 1947 is the earliest year for which reliable data can be found, and Japan was also involved in World War II till 1945. Therefore, the relevance of legal abortion in the decline of fertility is hard to test.
|-
| 1957-1973 || modest decrease followed by modest increase || CBR increased from 17.38 to 19.35 TFR increased from 2.058 to 2.135, dipping to about 1.9 in between 1959 was the first year with below-replacement fertility, and 1973 was the last year with above-replacement fertility || The year 1966, an inauspicious year for births, was in the middle of this period. Adjusting for the huge decline in births in these year and the subsequently slightly-above-normal value next year, we see a steady and modest increase in fertility over the period. Tightening of abortion laws is probably part of the explanation.
|-
| 1973-present || gradual decrease || CBR decreased from 19.35 to 8.5 TFR decreased from 2.135 to 1.361 || The decline was not steady, with small upticks in a few years, including what may be a more long-term rebound 2005-2009 (further data would be necessary to verify that). But the overall direction of decline is pretty strong. For a discussion of reasons, see [[explanations for fertility trends in Japan since 1973]].

==Total fertility rate==

===Total fertility rate broken down by birth order===

The columns TFR1, TFR2, TFR3, and TFR4 describe the total fertility rates at the respective birth orders 1, 2, 3, and 4. The column TFR5+ describes the total fertility rate at higher birth orders (combined). The corresponding "proportion" columns divide the corresponding birth order TFR column by the TFR column (the total across all birth orders). For each row, the proportion columns add up to 1.

===Data 1800 onward: lower quality data based on reconstruction from other data===

The data here are lower quality than the other data, even for recent years. They are based on various reconstructions and estimates, and are not sufficiently reliable for calculating year-on-year changes. However, broad trends may still be discerned.

An example to illustrate the lower quality of the Gapminder data is that the Gapminder data does not pick the sudden fertility dip in 1966, whereas the HFD data does.

The data sets correlate highly. For the years 1947-2009, where both data sets are available, the correlation is 0.993, indicating near perfect agreement in the ''trend''. The values themselves differ only slightly, both additively and multiplicatively, as the table below shows. If we exclude the anomalous year 1966 from the assessment, the correlation rises to 0.996.

Life table

== Definition ==

A '''life table''' is a table giving information on the survivorship rates at each age (i.e., the probability of survival from an age of <math>t</math> years to an age of <math>t + 1</math> years, for each integer value of <math>t</math>). Life tables are of two kinds.

=== Period life table (also known as static life table)===

A period life table, also called a static life table, is a life table where the survivorship probabilities for all ages are based on data collected in a single period (usually a year). Thus, a period life table for the year 1996 gives probabilities of survival at each age in 1996, i.e., it gives the probability that a person aged 40 in 1996 will go on to age 41, and also separately gives the probability that a person aged 60 in 1996 will go on to age 61.

A period life table cannot directly be used to compute life expectancy or probability of survival over a longer time than one period, unless we assume that the survivorship does not change over time.

=== Cohort life table (also known as dynamic life table) ===

A cohort life table provides information on the survivorship probabilities for a given cohort (by birth) at each age. For instance, a cohort life expectancy for the cohort born in 1970 will include the probability that people in that cohort will survive from age 25 to age 26, and separately that people in that cohort will survive from age 45 to age 46. Cohort life tables can be used to estimate life expectancy at birth as well as life expectancy for the parts of the cohort that survive to specific ages.

Combining cohort life tables for different birth cohorts presents a comprehensive picture of population dynamics.

Cohort life tables can includes estimates for survivorships in future years. These estimates can be made in various ways, and are subject to debate.

==Definition==

'''Period analysis''' is a method of aggregation used in demography to capture the entirety of behavior across a human life cycle by examining people at different age groups within a time period. The typical time period used for period analysis is a year.

=== How it works ===

==== The alternative of cohort analysis ====

Let us say that we want to measure the total number of times a person is expected to do some activity A in a lifetime. A "cohort" analysis would look at a bunch of people who have completed their lives and average out the number of times people in that cohort did activity A. There are two problems with cohort analysis:

* It is heavily delayed, since we have to wait for people's lifetime to finish (or the relevant part of their lifetime where they engage in activity A to finish) to obtain estimates. For measurements that change a lot over time, therefore, the values might come in too late.
* It relies on measurements having been taken in the past; if the measurements weren't taken previously, it may be hard to do a cohort analysis.

==== How period analysis gets over the problem ====

We illustrate the period analysis approach by using a period of one year.

Let's say our goal is to estimate the expected number of times a period will do activity A in a lifetime. For a year, we observe how many times people of each age do activity A. Then, we sum up the number (the "age-specific rate" values) across all ages to get a total rate.

The period analysis essentially answers the question: "If a person were to behave, at each age, like the people who are at that age right now, what would the person's lifetime behavior look like?"

The main problem with period analysis is that it does not correspond to the actual estimate of any specific cohort. In particular, in cases where [[tempo effect]]s are strong, it can be unreliable.

Female fertility

2017-01-21T04:12:08Z

Vipul:

==Definition==

The '''fertility''' of an individual female is defined as the number of [[live birth]]s of babies to that female. Note that the term '''fertility ''rate''''' is typically used when talking about aggregating fertility values across populations, but we simply talk of ''fertility'' when referring to a particular individual female. The fertility of an individual female is a nonnegative integer, i.e., it could take values 0, 1, 2, ... Due to biological considerations, it typically would not exceed 20 (there are only about 32 females in recorded history who have had more than 20 children, according to [[Wikipedia:List of people with the most children|Wikipedia's list of people with the most children]]).

Fertility is a loose umbrella term. The more technical terms are described below.

Note that in day-to-day parlance, fertility may be used in the sense of "ability to produce children." In demographic jargon, we use the term [[fecundity]] for that sense of the word fertility, and reserve the use of the term fertility for actual children produced so far or in the future.

==More precise jargon==

The following three terms are closely related:

{| class="sortable" border="1"
! Term !! Meaning !! is it constant or does it change with time? If so, how does it change?
|-
| [[Parity]] || The number of live births to a given female that have occurred ''so far''. || The parity of a female may change over time. Note that parity can either stay constant or increment by integer amounts over time, with the increments typically being by 1. Higher increments occur if the female gives birth to twins.
|-
| [[Completed fertility]] || The parity of a female who has completed her [[childbearing years]].|| It is constant (but can only be known once the female has completed her childbearing years).
|-
| [[Expected fertility]] || The value that the female expects for her completed fertility. This equals the sum of her parity and the number of future children she expects to have. || The expected fertility of a female may change with time, as her parity as well as her expectations and goals for the future change.
|}

There are many different ways of aggregating fertility across populations.

== Population-level fertility measures ==

{| class="sortable" border="1"
! Fertility measure !! Definition
|-
| [[Crude birth rate]] || Number of [[live birth]]s per 1000 members of the population.
|-
| [[General fertility rate]] || Number of [[live birth]]s per 1000 women in their [[childbearing years]].
|-
| [[Age-specific fertility rate]] || Number of live births to women at a given age, per 1000 women at that age.
|-
| [[Total fertility rate]] || Sum of age-specific fertility rates for all ages in childbearing years, but scaled to a denominator of 1 rather than 1000.
|-
| [[Cohort completed fertility]] || Arithmetic mean of the values of completed fertility for all women in an age cohort, typically one that has completed its [[childbearing years]].
|}

== Biological issues, exceptions, and branch cases ==

===Premature destruction of the fetus===

The typical path to a live birth is:

Conception <math>\to</math> Child grows in the womb for about nine months <math>\to</math> Child is born

The following are some subtleties associated with measurement:

* Many fetuses that are conceived spontaneously abort, often even before the to-be mother is aware that she is pregnant.
* In some cases, fetuses are aborted either due to [[induced abortion]]s or due to some physical accident or medical problem.
* In some cases, fetuses that survive to the point of birth die during the process of birth.

If any of the above cases occur, the fetus is ''not'' counted towards the female's fertility.

===Multiple births===

In some cases, a female may give birth to [[twins]] ([[identical twins]] or [[fraternal twins]]), [[triplets]], or higher forms of multiple births. Each live baby is counted as one, so giving birth to twins adds a total of 2 to the female's fertility.

===Egg donors, surrogate pregnancy, and adoption===

Three functions related to children can be conceptually separated, even though they are usually done by the same woman and/or family:

# Providing the egg that is used for conception, i.e., genetic parentage
# Bearing the fetus through the term of pregnancy and giving birth to it
# Taking care of the baby after it is born

The definition of fertility does not make a clear distinction between these tasks, though since births are what is recorded, (2) is the definition that is most likely to be used in practice. A few points:

* If either surrogate pregnancy or the use of external egg donors becomes quantitatively significant, then the distinction between (1) and (2) will start mattering.
* For the distinction with (3) to start mattering, adoption of babies and/or the use of both egg donors and surrogate pregnancies would need to be quantitatively significant.
* If we are measuring ''averages'' (i.e., ''rates'') across a population, then the distinction between (1), (2), and (3) is not relevant if all the people involved are members of the same population. If, however, the people involved are in different populations, it might matter. For instance, if there are adoptions in country A of babies from country B, then the distinction between (2) and (3) would matter in computing the fertility rate of country A. Similarly if people from country A use surrogate mothers from country B.

Life expectancy

2017-01-21T04:04:07Z

Vipul:

==Definition==

The '''life expectancy''' of an individual or a [[cohort]] is defined as the (average) expected number of years the individual or cohort will live. Life expectancies are based on estimates and projections about future developments that affect mortality, and hence estimates may differ. Note that life expectancy refers to the total number of years lived, rather than just to the number of additional years lived beyond the current age.

===Life expectancy at birth===

By default, reported life expectancy refer to life expectancy at birth. For instance, reported life expectancy in Canada in 1982 means the average life expectancy of a newborn baby in Canada in 1982.

|-
| scaling used to express the value || scaled to a denominator of 1, i.e., we report the TFR per woman || scaled to a denominator of 1000, i.e., we report the GFR per 1000 women. This is simply because the GFR value per woman would be too small, and we generally prefer to use a scaling where we get reasonably large and easily comparable numeric values.
|}

==Cases where they convey equivalent information==

TFR and GFR would be easily related in the following two cases:

* All the age-specific fertility rates are the same. In this case, the GFR would equal all the equal age-specific fertility rate values, and the TFR would be the product of that value and the number of childbearing years.
* The population size is the same for each age. In this case, the GFR would equal the average of the age-specific fertility rate values, and the TFR would be the sum of the age-specific fertility rate values. In this case again, the TFR would equal the product of the GFR and the number of childbearing years.

Of course, neither case occurs in practice: there is considerable variation in the age structure of the female population (see the [[population pyramid]] for more), and considerable variation in the age-specific fertility rates.

Bias in fertility estimation for recent migrants

2014-03-25T20:36:23Z

Vipul:

The [[total fertility rate]], used naively, is biased in how it estimates the fertility of recent migrants. The reason is as follows (explained step by step):

* Many females have their children in the few years immediately after migrating. They postpone children until they have migrated, and stop having children after the few years immediately after migration. A major driver here is marriages between male natives of the country and female migrants.
* In particular, this means that if a country has recently become a lot more welcoming of migrants than it was in the past, recent migrants are overrepresented in the migrant count at every age. Thus, all the age-specific fertility rates for migrants are inflated due to dominance by recent migrants. The total fertility rate is therefore also an overestimate.
* Even if there ''hasn't'' been a dramatic increase in migration, the age-specific fertility rates are still an overestimate, because the years spent by migrants prior to migrating, where they have low fertility, are not included in the denominator when computing age-specific fertility rates. For instance, the people who migrate at age 21 and then have children add to the fertility in that age, but the people who migrate later (say, at age 25) aren't being counted in the denominator for people at age 21.

==Qualitative history of fertility-relevant events and trends==

===Key events===

The event summary here is adapted from a discussion in ''What to Expect When You're Expecting'' by Jonathan Last.

{| class="sortable" border="1"
! Year !! Event !! Postulated effects seen in fertility statistics
|-
| 1938 || the state created the Family Code (Code de la famille ), which provided an annual stipend (colloquially known as the “Housewife’s Allowance”) to parents for each child. || data unavailable
|-
| 1978 || Housewife's Allowance was abolished, replaced by state-run day-care centers and a National Family Allowance Fund. The stipend just covered the costs of sending the kids to the new day-care facilities. || downward trend in fertility reversed for the 4-5 years immediately following the change, but then resumed.
|-
| 1997 || "New Family Policy" that provides increased subsidies to families with multiple children, with the per-child subsidy increasing as the number of children increases. || downward trend in fertility reversed following the change, but the contribution of the change is unclear (because much of the increased fertility was from recently migrated people and the persistence of the fertility increase may have been due to more migration rather than the policy changes).
