SELEGA, Liberia — The deep distrust of government created by years of war is evident in Liberian villages like this one, where people don’t understand why census workers have been chalking numbers on every house, lean-to, hut, and shack.

“What do you think they want with my house?” a 70-year-old woman, Monogo Kebeh, said outside her mud hut.

The census is an exercise as old as the Roman Empire, but in a country that has not had a one for a quarter century it’s anything but ordinary. For more than a year, over 9,000 census-takers have combed the densely forested nation mapping every structure. For three days starting Friday, they will revisit each dwelling and count the inhabitants.

The preparations, including the marking of dwellings, have given birth to rumors. Some wonder if its part of a military recruitment drive, a potent fear in a country where boys as young as 5 were handed machine guns and forced to fight. Others believe it’s in preparation for new taxes.

To try to dispel these and other rumors, the government commissioned a pop star to compose a catchy tune about the census. It’s been translated into Liberia’s 16 languages and is playing daily on the radio, urging Liberians to “stand up and be counted.”

Throughout the country’s interior, billboards have been erected reminding villagers to stay home for three days starting Friday to properly be counted. Schools are closed through the end of the census.
