The Population Investigation Committee is a United Kingdom social research group founded in 1936 by the council of the British Eugenics Society.
Entitled ‘Eugenics in the Light of Population Trends’, Carr-Saunders's lecture drew attention to the falling birth rate in Britain and his fears for what this meant for British society.
[5] It was towards these ends that the Council of the Eugenics Society formed a research body – the Population Investigation Committee - in 1936.
As such, the PIC played a major role in a number of national surveys which sought to investigate the "medical, economic and social factors affecting changes in the population".
[10] Other research activities of the PIC included inquiries and surveys into fertility and birth control; marriage and divorce and the British Peerage.
