Who’s hiring? Some of the strongest data this year come from the professional and business services sector, usually associated with white-collar employment. Employers in this broad category have added jobs for eight consecutive months, 572,000 from January through June. The sector accounted for more than 16.7 million U.S. jobs in June. The information technology sector outperforms most others. IT employment in computer systems design grew to 1,441,000 positions this June from 1,426,900 in December 2007. Similarly, hiring continues to rise for custom computer programmers, whose employment numbers in June stood at 626,000, up from 620,000 in December 2007.
