	The ~~second~~ and ~~fourth~~ columns are not standard demographic variables but have simply been computed to give a better intuition about the maximum extent to which abortion availability could have directly affected fertility. In particular, note that abortions undertaken in a given year may substitute for a birth ''next'' year, so the year-to-year data has some inconsistencies. Also, because detailed age-specific abortion data was not available, the abortion-adjusted TFR does not take into account the age distribution of abortions but simply uses the abortion ratio to adjust the TFR (in the same way as for the CBR), therefore the measure is incorrect.

Abortion data is obtained from [http://www.johnstonsarchive.net/policy/abortion/ab-japan.html Johnston's archive], which in turn relies on a variety of sources. Data is not of high reliability.

Fertility data referenced on this page is drawn from the [[Human Fertility Database]], which is of high reliability. The UN data and the HFD data correlate highly, even though the former is slightly less accurate, so the inconsistency in data sources should not affect broad conclusions.

==Qualitative history of relevant events==

See [[Wikipedia:Abortion in Japan]].
{| class="sortable" border="1"
! Year !! Event !! Postulated effects seen in abortion statistics
|-
| 1869 || abortion was banned nationwide, but punishment was rare except in cases of adultery or death to the mother ||
|-
| 1880 || ban on abortion was included in the penal code ||
|-
| 1907 || women could be incarcerated for up to a year for having an abortion; practitioners could be jailed for up to seven. ||
|-
| 1923 || doctors were granted legal permission to perform emergency abortions to save the mother's life; abortions performed under different, less life-threatening circumstances were still prosecuted. ||
|-
| 1940 || National Eugenic Law outlined a set of procedures doctors needed to follow in order to get an abortion. ||
|-

|-
| 1996 || replacement of the Eugenic Protection Law by the Maternal Health Protection Law, making abortion illegal except in case the fetus had significant defects or in case of danger to the mother's health || No discernible effect, but probably because the law itself didn't change reality on the ground.
