The growing population of the United States and an increased need for human services changed the role and expectations of nonprofit organizations in the community. Further, disease, war, economic swings, and natural disasters also brought an opportunity for expanded social services programs through nonprofit organizations. Beginning with President Eisenhower in 1955, policy called for less reliance on the government for goods and services demanded by citizens and more reliance on the private sector. The Public Assistance Amendments of 1962 and 1967 followed Eisenhower's policy due to the War on Poverty and the Great Society programs of the Kennedy and Johnson administrations, which created widespread contracting between government and nongovernmental agencies. Today, there is a White House Office of Faith-Based and Neighborhood Partnerships within the President's Executive Office, strengthening the nonprofit sector and its partnership with the federal government.
