The AIWC's support for BC broadened year by year. First it appealed to municipalities and local bodies to establish birth control services, then to its own branches. In 1940 (Allahabad meeting) they called family planning "of the first importance to India's health and asks that medical officers connected with all municipal and Government Women's hospitals, dispensaries and health centers should be authorised to give advice to married women desiring this assistance in spacing their families." If there was official government opposition to the idea, AIWC branches were to open birth control clinics,  especially in "mill areas and poor localities under adequate medical supervision." Branches should also undertake spreading propaganda. This resolution emphasize "spacing of births," while by 1941 they were accepting more broad rationales.
 National Government did not weigh in much, but in 1941 P.N. Sapru introduced a motion to the Council of States in New Dehli that the Council recommended that "in view of the alarming growth in population in India, steps be taken to popularise methods of birth control and establish birth control clinics in centrally administered areas. Resolution passed 9-8. Five years earlier they had voted down a similar measure.
This resolution does not appear to have made any direct impact on Provincial Governments, except that of the Punjab. There, Col. PC Bharucha, Inspector General of Civil Hospitals initiated family planing activities in the Province in 1941. Rena Dutta contacted a number of people in the Punjab, and while they agreed with the need for more birth control and services in hospitals, and other health centres, "there was opposition to form a family planning society."They also called for more education, raising the age of consent, and giving advice to more mothers and fathers. In 1942 they passed the laws and trained women doctors, making it the first in British India to teach a programme in health prospects.
World War II  "Family planning activities both in India and abroad came to a almost stand still" during WW2. Even the League of Nations' "feeble attempt in the population field" to study demography and its relation to economic, financial and social situation was not completed.  The British FPA picked up a few Indians as Vice-Presidents, Lady Cowesji Jehangir and Rani Laxmibai Rajwade. Only after the war did the movement start to revive. Organizations in India had lost their vigor.  Main source of information after the war was the ICPP
