> 100 years ago there's NO statistic for child under 13yo death rate

100 years ago was 1920. Many countries absolutely had infant mortality statistics by 1920.

See R.A. Meckel's "American public health reform and the prevention of infant mortality, 1850-1929" which (as the name implies) goes back was more than 100 years.
