This manual and codebook has been developed as a companion to the 2019 NSECE home-based provider quick tabulation data file for unlisted providers. Unlisted home-based providers were identified through household screening. There is a separate quick tabulation data file for listed providers which are those who were identified through and sampled from state-level or national administrative lists. Section 1.A provides additional detail on the home-based provider survey and its sampling methods. This manual has been designed to introduce users to the NSECE and the data available for analysis. It also offers an overview of key concepts important for the analysis of the unlisted home-based provider data. Section 2 of this manual contains detailed codebook entries for each variable contained in the 2019 NSECE home-based provider quick tabulation data file for unlisted providers. (author abstract)
