Aims to investigate the types of romantic relationships that produce early and/or unintended pregnancies. Based on a representative sample of 1,003 women aged 18 to 22 residing in Genesee County, Michigan. Genesee County, Michigan was selected for the RDSL study due to the significant number of African Americans residing there, and because the area is characterized by significant variation in economic circumstances, allowing the collection of data from poor African Americans, poor Whites, middle-class African Americans, and middle-class Whites within a single geographic area. Data collection for the baseline survey was conducted March 2008 through July 2009. The baseline survey was followed by a series of 3 supplemental surveys administered over a two-and-a-half year period between May 2009 and August 2011.
