Use -foreach- with -levels-. More generally, 
see 

http://www.stata.com/support/faqs/data/foreach.html

gen P0 = . 
gen P1 = . 
gen P2 = . 
levels region, local(R) 

qui foreach r of local R { 
	povdeco pcexp [aw=wei] if region==`r', pl(20000)
	replace P0 = $FGT0 if region == `r'
	...
} 

tabdisp region, c(P0 P1 P2)
