Every 10 years, as mandated by the U.S. Constitution, our nation conducts a census, which is an effort to count every person in the United States. Every resident in the City of Mount Vernon included in 2020 census means more funding for jobs, housing, health care and library services. More hope for Mount Vernon. More promise for Mount Vernon.
