George W. Grier, 85, a demographer who for many years conducted wide-ranging studies of population trends, education and economics, died Nov. 6 at the Maplewood Park Place retirement facility in Bethesda. He had Alzheimer’s disease, his wife, Eunice Grier, said.

Mr. Grier, who was a longtime Bethesda resident, came to the Washington area in 1960 to work at the Brookings Institution. He was a deputy city administrator in the D.C. government in the 1960s. He also worked for the old Greater Washington Research Center, where he was vice president from 1967 to 1976.

After 1976, he and his wife operated the Grier Partnership, which conducted dozens of studies for school systems, municipal governments and businesses.

Over the years, Mr. Grier was among the first to enumerate the changing demographics of the District and Prince George’s County, as well as the growing affluence of the Washington region.

George Washington Grier was born in Glenside, Pa., and was a Navy veteran. He was a 1950 graduate of the University of Pennsylvania, where he was elected to the Phi Beta Kappa honor society. He received a master’s degree in psychology from Penn in 1952.

Mr. Grier worked for the New York state government before moving to the Washington area. He was a member of Lambda Alpha International, an honorary society for land economics.

Survivors include his wife of 63 years, Eunice Sheridan Grier of Bethesda; two daughters, ­Sheryl Grier of Upper Marlboro and Suzanne Grier of Austin; and three grandchildren.
