The Population Research Center on UT’s campus has restricted information on population health and well being, reproductive, maternal and infant health, family demography and human development and education, and institutions. If your research falls into this realm, you can apply to use their data, but you should first contact an Administrator to see if your proposal is feasible. Using this type of data requires a duty of care, because it is typically private. However, the data can be used if it is required for the research project, and the researcher keeps the data secure. https://liberalarts.utexas.edu/prc/
