The standard error σ of estimates of poverty rates at a point in time isσ=α ⋅ pˆ⋅ ( 1 − pˆ).nIf the scorecard has already been applied to a sample n, then pˆ isthe scorecard’s estimated poverty rate, and the confidence interval c = +/– z ⋅ σ .33
8. Estimates of changes in group poverty rates over timeThe change in a group’s poverty rate between two points in time is estimated asthe change in the average poverty likelihood of the households in the group.8.1 Warning: Change is not impactScoring can estimate change. Of course, change could be for the better or for theworse, and scoring does not indicate what caused change. This point is often forgottenor confused, so it bears repeating: poverty scoring simply estimates change, and it doesnot, in and of itself, indicate the reason for the change. In particular, estimating theimpact of program participation requires knowing what would have happened toparticipants if they had not been participants (Moffitt, 1991). Knowing this requireseither strong assumptions or a control group that resembles participants in all waysexcept participation. To belabor the point, poverty scoring can help estimate programimpact only if there is some way to know what would have happened in the absence ofthe program. And that information must come from somewhere beyond poverty scoring.Even measuring simple change usually requires assuming that the population isconstant over time and that program drop-outs do not differ from non-drop-outs.8.2 Calculating estimated changes in poverty rates over timeConsider the illustration begun in the previous section. On Jan. 1, 2009, aprogram samples three households who score 20, 30, and 40 and so have poverty34
