Business is booming in Washington, as a careful study of this year's annual survey of top area enterprises will show. The Washington Post's annual report on these businesses has been expanded this year to 50 corporations and quasi-government operations from 40 in recent years.

The growth of the annual survey merely reflects the growth of the private sector in the Washington area. While the federal government remains dominant, the percentage of government workers in the regional payroll is declining. Several of the companies on this year's list are the subject of takeover battles and mergerbids. A significant percentage of the Top 50 had record earnings in the most recent year.

Companies listed here have headquarters in the area and are the largest firms in terms of assets, revenues, employes or influence within their economic sector. Annual financial figures are for calendar 1977 unless otherwise noted. If a company is traded publicly, its exchange is listed in parentheses - NYSE for New York Stock Exchange, Amex for the American Exchange, P for Philadelphia and OTC for over the counter. Utilities

Begun in 1971 as a successor to the old Post Office Department, the Postal Service faces an array of challenges that looks almost impossible to surmount: the necessity of reaching agreement this year with postal workers on new labor contracts, keeping mail volume up in the wake of higher rates that took effect electronic message transfer needs of the future, and balancing its budget.
