SIPP uses a complex sample design that has important implications for the estimation of standard errors. Because the SIPP design is not a simple random sample, the standard errors reported by most off-the-shelf statistical software will underestimate the true standard errors of estimates from SIPP. (See Chapter 7 of the SIPP Users' Guide for details.) A detailed description of the SIPP sample design and standard error calculations can be found in the third edition of the SIPP Quality Profile, 1998 (U.S. Census Bureau, 1998a).
