To support population research at UCLA, CCPR maintains major demographic datasets in ready-to-use formats, provides access to data through the CCPR and ISR Data Archives, supports the preparation of data for public use, maintains a database about data from developing countries and provides a facility for secure data analysis. ReadyData services are provided to CCPR affiliates to reduce the costs of doing high quality empirical research in the population sciences.
ReadyData provides affiliates with access to commonly used population survey and census data in a format that is convenient for statistical analysis. All datasets are stored in ready-to-use labeled Stata files on CCPR Windows Domain (DFS) along with electronic documentation. To get to ReadyData, please log on to your local CCPR Windows workstation and navigate to the auto-populated R:\Data DFS file space. Datasets are added to ReadyData on the basis of affiliate demand. Datasets that are or are likely to be widely used by affiliates or will be intensively used for extramurally funded research projects are good candidates for the ReadyData archive. Please email email@example.com if you would like to suggest that a dataset be added.
Files in the ReadyData archive are structured in as intuitive and consistent way as possible. Some datasets are available in products other than Stata. If you want data in a different format, please email firstname.lastname@example.org. We do our best to keep datasets up to date. If you think datasets are not up to date, please email email@example.com. If you need older versions of datasets, please let us know and we will extract them from our archive.
Some datasets such as CPS can be used without prior permission.
Other datasets, such as HRS and AHEAD require you to first register as
a user on their own web site prior to using the data. Current hosted
