Reducing the size of the sample increases the level of statistical error. Although the reduced sample will still provide reliable estimates on a national basis, state level data for most states will no longer be available.

The SIPP is the only instrument providing data to support analysis of program effectiveness.
It is one of the most important surveys the government conducts -- the only large-scale measurement of the impact of Medicaid, food stamps, school lunches, unemployment and other safety-net programs for the poor… Public officials and researchers rely on those findings to determine how government programs are used, which are most effective and which are faltering.
Even Ralph A. Rector, senior research fellow at the conservative Heritage Foundation, opposed the cut.
"The worst outcome is if the money is insufficient for the SIPP and they don't continue" working on an alternative, he said. Then researchers don't get good survey data now or a reliable replacement later, he said.
But the Bush administration is firmly committed to faith based decision making. And they’ve been cutting all those programs that SIPP monitors, anyway, so why would anybody be interested in the impact?
