Every 10 years, the US Census must be completed.

It begins on April 1, but preparations are already underway.

Representatives from the US Census say it's crucial as many people as possible are counted, "this is the greatest impact for the next decade of funding, one person missed is about 2,000 dollars a year. When you think about that over the next 10 years per person that adds up very quickly," said Eric Friedlander, the Deputy Secretary, KY Cabinet for Health and Family Services.

To assure as many people as possible are counted is challenging, especially counting "vulnerable" populations. To help reach this group the US Census Bureau has representatives in places like city parks, soup kitchens, hospitals, and prisons.

College students and babies are another group that has been historically undercounted.

Representatives say it only takes about 4 minutes to complete the census survey. It can be done by mail, by phone, or online.

The US Census is looking for temporary workers, they pay $19 an hour, plus mileage.
