THE Ministry of Planning will start work on the Kingdom’s first economic census this month, a government official said Monday, although the final results won’t be completed until March 2012. San Sy Than, director general of the National Institution of Statistics and secretary of the National Census Committee, told the Post Monday that after initial tests, a larger pilot survey will start in March. The total budget will be US$3.5 million with Japan providing $2.8 million and the government making up the shortfall, Chhay Than, senior minister at the Ministry of Planning, told a press conference Monday.
