Description

MULTYEAR identifies the actual year of survey in multi-year ACS/PRCS samples.

For example, the 3-year ACS and PRCS data files each include cases from three single-year files. For these multi-year samples, the YEAR variable identifies the last year of data (2007 for the 2005-2007 3-year data; 2008 for the 2006-2008 data; and so on). MULTYEAR gives the single-year sample from which the case was drawn (2005, 2006, or 2007 for the 2005-2007 3-year data; 2006, 2007, or 2008 for the 2006-2008 3-year data; and so on).

This variable is valid only for multi-year ACS and PRCS samples. MULTYEAR is a 4-digit numeric variable which reports the actual year of survey in multi-year ACS/PRCS samples. MULTYEAR specific variable codes for missing, edited, or unidentified observations, observations not applicable (N/A), observations not in universe (NIU), top and bottom value coding, etc. are provided below if applicable by Census year (and data sample if specified).
