LOCATION -- Glenarden is 10 minutes from the District line, mostly inside the Capital Beltway (I-95) just south of its intersection with Rte. 50.

RACIAL MAKEUP -- Glenarden is more than 95 percent black.

DESCRIPTION -- When Glenarden was incorporated as a town in 1939, Mayor James Fletcher says, it was not uncommon to see chickens in the yards and pigs in the muddy streets. But in the 1950s, Glenarden became the cutting edge of black suburbanization. While it does have garden apartments that recently have been the scene of drug-related violence, today the town consists mostly of middle-class single-family detached houses. The first houses built typically had three bedrooms and one bathroom, were covered with aluminum or asphalt siding and sat on 8,000-square-foot lots. By the late 1960s, in the Fox Ridge section, lot sizes of as much as a half-acre were established, and basements, garages, carports and brick veneer houses increased in number. Today, fairly luxurious houses are planned for a development called Glenarden Estates.

COST OF HOUSES -- Most common: $100,000. Some of the earliest suburban housing that has not been renovated is still available for less than $70,000, and some of the newest houses are projected to cost more than $150,000.

POPULATION -- Many members of the first wave of black suburbanites who moved from the District in the 1950s and 1960s still live in Glenarden, giving it a large number of people in their forties and fifties who have children in their teens and early twenties. Many Glenarden residents are employed at supervisory levels in the federal government.

SAMPLE FAMILY -- Arthur M. Smith, 57, is a GS 13 accountant with the Maritime Administration, which is part of the Department of Transportation. His wife Mildred S. Smith is a GS 6 research data assistant in the epilepsy branch of the National Institutes of Health, where she has worked for 25 years. They bought in Glenarden in 1964 when, they recall, Martin Luther King Jr. Highway was a narrow road; their friends thought of the area as "the boondocks," and their new house cost $17,500. Their son DeMaurice F. (Dee) Smith, 23, is in his second year of law school at the University of Virginia. Their daughter, Cheryl L. Smith, 21, a junior at the University of Maryland, is interested in fashion merchandising. They put the value of their three-bedroom, two-bath house with small in-ground pool in the $100,000-$110,000 range.
