Woodrow Ginsburg, 93, an economist and former union employee who helped start the Center for Community Change, a nonprofit public policy organization that seeks to improve living standards for low-income Americans, died May 31 at a hospice in Baltimore. He had pneumonia.

Mr. Ginsburg was a research director for the United Rubber Workers, the United Auto Workers and the AFL-CIO before he helped create the Washington-based Center for Community Change in 1968. He became chief economist of the organization.

After retiring in 1991, he volunteered as chairman of the economic policy committee of Americans for Democratic Action, a prominent liberal advocacy organization. He also taught at the George Meany Center for Labor Studies, a Silver Spring institution named after the labor leader and now known as the National Labor College.

Mr. Ginsburg was a native of Newark and a 1940 economics graduate of Rutgers University. He did graduate work in economics at American University. A heart murmur kept him out of the military during World War II; he spent the war working for the National War Labor Board.

An Alexandria resident much of his life, he moved only recently to Silver Spring. He did volunteer work for the Democratic Party in Northern Virginia, and his memberships included the American Civil Liberties Union and the Sierra Club.

Survivors include his wife of 63 years, Marjorie Gallant Ginsburg of Silver Spring; two sons, Larry Ginsburg of Phoenix, Md., and Roy A. Ginsburg of Minneapolis; a sister, Sorelle Feldberg of Baltimore; and five grandchildren.
