Preliminary Report: The 2001 Fertility and Reproductive Health Survey (FRHS) is the third survey to obtain detailed information on demography and reproductive health in Myanmar. The first survey was 1991 Population Changes and Fertility Survey (PCFS) and the second was the 1997 FRHS. This Preliminary Report is the first report of 2001 FRHS to provide policymakers, programme managers, international organizations, NGOs and scholars timely and reliable detailed but brief information on fertility, contraception, maternal and child health, infant and child mortality, knowledge of STDs and HIV/AIDS and internal migration in Myanmar. Two more detailed reports are planned to supplement this one: comprehensive Country Report (main survey report) and Report on Detailed Analysis of Trends and Patterns on selected topics.
