The 2015 National Content Test (NCT) is the primary mid-decade opportunity to test content on a nationally representative sample as part of the research and development cycle leading up to the re-engineered 2020 Census. In addition to testing content modifications, the 2015 NCT also tested different contact strategies designed to optimize self-response and different approaches to offering in-language materials. The 2015 NCT employed a complex sample design to select 1.18 million stateside housing units and 20,000 Puerto Rico housing units. The work presented describes the coverage, race, and response propensity strata that were assigned, as well as how the 1.18 million stateside housing unit sample was selected using these strata.
