The impact of the UCS on mitigating health impoverishment was as impressive
at the subnational level as it was at the national level. As shown in Figure 15, the
province-specific incidence of impoverishment reduced significantly after 2002,
when the UCS was implemented nationwide. In the poorest rural northeast region
of Thailand, the number of impoverished households dropped from 3.4% in 1996
to 2.3-2.4% in 2002-2004 and to 0.8-1.3% in 2006-2009.
