This dataset, japan_birth_stats_tbl_df, is a tibble containing Japan’s birth-related demographic statistics from 1899 to 2022. The dataset includes birth counts by gender, birth rate, fertility rate, infant deaths, stillbirths, birth order, gestational weeks, average parental ages, and legitimacy of births. Some data are missing between the years 1944 and 1946 due to records lost during World War II. The dataset preserves the original structure from its source on Kaggle.
