Lion SODAPOP - Lite:
PRMIHS - Puerto Rican Maternal and Infant Health Study

The Population Research Institute (PRI) is currently evaluating the SODAPOP service. The ability to extract a data set containing a subset of variables will not be supported after September 15, 2016.

The data collections in SODAPOP will still be available from the PRI. If you should have concerns about this change to the SODAPOP service or need to access some of the data, contact the PRI's Computational and Spatial Analysis (CSA) core at

Data Format SAS version 9 data table (other formats available through SodaPop)
Sampling Independent live birth and infant death samples drawn from birth certificates and death certificates. Birth sample stratified by vital statistics reporting area, month, and infant birth weight (less than 2500 grams; 2500+ grams). Death sample was based on the full population of infant deaths.
Weights The final birth sample weight is the product of three weighting factors: (1) the inverse of the probability of selection, (2) a nonresponse adjustment, and (3) a poststratification adjustment. Failure to weight the PRMIHS birth sample data will lead to biased population estimates because some births are overrepresented and others are underrepresented. Because the full population of infant deaths was drawn for the death sample, the final death sample weight is based on only one factor: a nonresponse adjustment.
Universe Puerto Rican women who had a live birth or infant death in the study area (Puerto Rico, Connecticut, Florida, Massachusetts, New Jersey, New York City, Pennsylvania) between July 1, 1994 and December 31, 1995.
