During the decade from 1970 to 1980, the Washington area became increasingly top heavy, with the largest employment growth occuring among managers and adminstrators, according to an analysis of Census data by the Metropolitan Washington Council of Governments.
The number of managers and administrators grew by 133 percent over the decade, making it the second largest employment category after secretaries. The rate of growth in the numbers of secretaries was below average. The third largest group of employes was general office clerks. Together, the three occupations accounted for nearly a quarter of a million workers.
The report portrays a work force that demonstrates trends predicted for the nation as a whole, a work force that is becoming increasingly technical, professional and clerical, with little room for less skilled employes except in the services.
The number of computer systems analysts increased by 93 percent and computer programers increased in numbers by 73 percent. Such service occupations as guards and private police and nurses aides grew by 125 percent and 132 percent, respectively.
The number of typists declined by 9,520, the largest decline registered for any occupation. The number of workers employed in skilled crafts or production increased at a lower than average rate.
The report also identifies several Washington specialties:
* The number of lawyers increased 103 percent in the recently ended decade. Recently there has been speculation that deregulation may have slowed growth in the number of attorneys, but at the end of the 1970s it was the fifth largest employment category in the area. In fact, the area had one lawyer for every 100 residents, five times higher than the national average.
* The area also had one out of every seven geographers and environmental scientists in the United States; one out of every nine economists; one out of every 12 technical writers and one out of every 12 mathematicians. Perhaps one reason that such a wealth of data is available is that the area also has one out of every seven statisticians in the United States.
* The area also has one out of every nine management analysts; one in 10 public administrators and officials and one out of every 17 reporters and editors.
Washington has the highest proportion of its employment (36 percent) in government, despite its relative decline in importance as an employer. It also has the highest concentration (40 percent) of workers in executive, professional and technical jobs. Boston is next with a mere 34 percent.
