Taking into Account the Fact That Some Providers Are Open More than Four Hours a Day (3.8.4)

In the 2001 data collection and analysis, we assumed that the observation period (including observations of number of clients) was the same as the period that providers were open. By the time of the 2005 survey, we had realized that this is not always true, and we built into the weighting algorithm an expansion factor to allow for clients who may have come on the day of sampling but not while the observers were there. This expansion factor is defined in Equation B-25 of Technical Appendix B.
