Gross reproduction rate (GRR)

Sum of age_specific_fertility_rate()'s asfr_female (female births per woman): expected daughters per woman, ignoring mortality. Uses INE's births by sex of the newborn directly rather than scaling the TFR by an assumed sex ratio at birth.

gross_reproduction_rate(asfr_df)

Arguments

asfr_df

Output of age_specific_fertility_rate().

Value

A tibble with nuts3_code, province_name, year, grr (daughters per woman).

Examples

asfr <- tibble::tibble(
  nuts3_code = "ES111", province_name = "A Coruna", year = 2023,
  age = c(20, 30), asfr = c(0.03, 0.08), asfr_female = c(0.015, 0.04)
)
