Thursday, April 1, is the deadline to turn in the Census form.
So far, about 62 million households have returned the forms. That's about 52 percent of the population.
The government is looking to increase that number with a series of rallies across the country on Thursday.
Several regions are being urged to increase their response rate, including Alaska, New Mexico, Louisiana, New York, and Texas.
The ten question form counts residents and gathers demographic data. The data is used to distribute federal aid and to allocate seats in the House of Representatives.
If the Census form is not returned, a second form will be mailed. Starting next month, Census workers will begin knocking on doors if you did not return the form or did not fill it out completely.
