Russian Fertility Database

The Russian Fertility Database contains in separate files period and cohort fertility indicators for Russian women. The format of the files is .xlsx.

Fertility rates for the period from 1946 to 2022:

• Age-specific fertility rates by 1-year age groups and age-specific fertility rates by 1-year age groups and birth order;

• TFR and TFR by birth order;

• Mean age at birth and mean age at birth by birth order.

Fertility rates for the female cohorts from 1932 birth year onward:

• Cohort age-specific fertility rates by 1-year age groups for female cohorts born between 1932 and 1988 for all births and by birth order;

• Cumulative fertility rates by age x by 1-year age groups for female cohorts born between 1932 and 1988 for all births and by births order;

• Cumulative fertility rates by age 40, 45, and 50 for female cohorts born between 1932 and 1984 for all births and by birth order;

• Mean age at birth by ages 40, 45, and 50 for female cohorts born between 1932 and 1983 for all births and by birth order;

• Fertility tables for female cohorts born between 1932 and 1988;

• Cohort parity progression ratios by ages 40, 45, and 50 for female cohorts born between 1932 and 1984; 

• Parity distribution by ages 40, 45, and 50 for female cohorts born 1932-1984. 

 

Input data:

All indicators presented in the database are calculated on the basis of population statistics data from the Federal State Statistics Service

Birth rates for 1946-1958 are calculated on the basis of the numbers of births by birth order and mother's age for 1946-1958 and population data for 1946-1958 presented in the book Andreev E.M., Darsky L.E., Kharkova T.L. (1998) Demographic History of Russia: 1927-1959. M.: Informatika. 187 p.

Birth rates for 1959-2022 are calculated on the basis of the numbers of births by birth order and mother's age for 1959-2022 and data on the age distribution of the population for 1959-2023.

Data limitations:

1) The Federal Law of 15.11.1997 N 143-FZ "On Acts of Civil Status" excluded the birth order from birth registration acts, so in 1999-2010 in many regions data on the birth order was not available.  In order to obtain age-specific birth rates by birth order, a proportional distribution by birth order was carried out in 1997-2010. 

2) Numbers of births by mother's age for the period 1956 to 1958 and numbers of births by mother's age and birth order for the period 1955 to 1977 were developed by five-year mother's age groups only and were interpolated by one-year ages using a quadratic spline function.

3) Territorial coverage: for the purpose of cohort comparability, all indicators are presented for Russia in the borders up to March 17, 2014.
