Both the KDICP and the MDICP aimed to examine the role of social interactions in changing demographic attitudes and behavior. The first two waves of the MDICP (carried out in 1998 and 2001) focused on two key empirical questions: the roles of social interactions in (1) the acceptance (or rejection) of modern contraceptive methods and of smaller ideal family size and (2) the diffusion of knowledge of AIDS symptoms and transmission mechanisms and the evaluation of acceptable strategies of protection against AIDS. Beginning with the third wave in 2004, the MDICP expanded in several directions: (1) A sample of adolescents (age 15-24, married and unmarried) was added to the base sample of ever-married women and their husbands, (2) Biomarkers for HIV and other sexually transmitted infections were collected from all respondents who consented, and the results were provided to those who requested them, (3) GPS coordinates were collected for all sampled households. 2008-05-21 survey data 20840 10.3886/ICPSR20840.v1 Africa Global Malawi 1998 2001 ICPSR metadata records are licensed under a Creative Commons Attribution-Noncommercial 3.0 United States License (http://creativecommons.org/licenses/by-nc/3.0/us/).
