Data Collection
The following grid shows the years in which the NLTCS and its supplements were conducted. A 'Y' indicates that a given survey was conducted in that year. Clicking on a 'Y' brings up the appropriate metadata screen, which has some basic information about that survey: sample size, questionnaires, and other documentation as appropriate. The metadata information will be significantly augmented in later website releases. As it stands, the grid can serve as a quick reference to the entire NLTCS. Detailed information about each survey component can be found in the 'Data' section of the website.
