The Martin Luther King Jr. Center for Nonviolent Social Change
A formal letter from the Joint Center for Urban Studies of MIT and Harvard University invites Dr. King to a Conference on Social Statistics and the City at Executive House in Washington, DC, June 22 and 23, 1967. Signed by Director Daniel P. Moynihan, the correspondence cites the inadequacy of the 1960 US census in enumerating the Negro, Puerto Rican, and Mexican populations, a concern about the impact on voting rights, and the need for better enumeration in the 1970 census.
