Data on completed fertility
This data is from the Human Fertility Database. Max Planck Institute for Demographic Research (Germany) and Vienna Institute of Demography (Austria). Available at www.humanfertility.org (data downloaded on December 2, 2013, last updated August 8, 2012).
The CCF column denotes the completed fertility rate for the birth cohort born in that particular year, and the CCF40 denotes the parity at age 40 for the birth cohort born in that particular year. CCF40 values cannot be available for birth cohorts born less than 40 years ago, whereas CCF values cannot be available for birth cohorts born less than 49 years ago.
| Cohort | CCF | CCF40 | CCF1 (proportion that have a first birth) | CCF2 (proportion that have a second birth) | CCF3 (proportion that have a third birth) | CCF4 | CCF5+ (sum of CCF5 and higher values) |
