Even though the government gives equal pay for equal work, everybody knows that men in government make more than women in government. But do you know how much more? Would you believe almost $11,000 per year more? Believe it.

In what is certain to be an eyeball-popping figure in Cincinnati, Peoria or just about any other city, be advised that the average "white collar" civil servant in Washington, D.C., now gets $21,998 per year. That figure was compiled by taking all the 277,000 white collar professional, technical and clerical people here make, and averaging it out.

Within the $21,998 average per year, men typically get $27,132 while the average for women is $16,511.

Any and all-of-the-above salary figures is mind-boggling for an average American commuinty. But nobody ever said Washington, dependent as it is on the federal government for jobs and paychecks, is average.

Outside of Washington the typical U.S. civil servant averages about $3,000 to $4,000 per year less. The $ $ $ dominance of men over women is true, however, in federal offices from Kansas to California.

The reason for the pay differentials by sex, and by geographic reasons are explainable, although not everybody likes the explanation or is willing to accept the conclusions. Washington is a high-salary town because this is headquarters. Eight out of 10 career federal executives lives here and nearly 100 percent of the important, and higher paid political appointees (whose salaries are NOT included in the averages) lives here.

Excluding pay of political appointees, members of Congress and congressional aides and judicial pay, the highest salaries in government go to professionals. Even within the porfessional pay range, which today averages almost $27,000, men still make between $8,000 and $9,000 more than women.

Administrative pay in the Civil Service Commission nationwide study of federal salaries averaged $22,000 in October, 1977 (before the recent 5.5 percent raise) with women in lower grades averaging $6,000 per year less than male counterparts. Even in the technical and clerical jobs, men who tend the head offices and divisions had a higher annual average salary than women.

Men make more money here because they are-in most agencies and private offices-the bosses. The average male civil servant has much longer service than the average woman employe and more professional, or job related training. But that is changing rapidly as the number of working women increase in the federal and private work force, and as women move into legal, engineering and other professional jobs and careers where once they were novelties.

Ironically, women do almost as well as men in the paycheck department in blue collar federal jobs. Although most of the mechanical, craft and laboring positions are held by men, there is only a $2,000 to $3,000 difference between pay for men and women in the blue collar field.
