WASHINGTON (Bloomberg) — Mismatches in supply and demand for educated workers boost US unemployment and add as much as two percentage points to the jobless rates for some cities, according to the Brookings Institution.Cities with larger gaps in education levels between workers and available positions have lower rates of job creation and new openings, the institution’s Jonathan Rothwell said in a report published Wednesday.San Francisco, Washington and San Jose, Calif., have the most demand for college graduates, according to the report.“It’s harder for employers to fill open positions if they’re in metro areas with a low-educated workforce,” Rothwell said. “There are very few job openings available for workers with less education. We need to create more openings for middle-to-lower educated workers.”Jobs in the 100 largest metropolitan areas require more education than the work force can provide, according to the analysis of online employment postings, occupations and educational attainment from January 2006 to February 2012.A bachelor’s degree or more is required for 43 percent of jobs, while 32 percent of adults ages 25 and older have attained that education level, according to Rothwell, a senior research associate at Washington-based Brookings.“Metro areas with the most highly educated workers relative to demand also have the lowest unemployment rates for both less educated and less experienced workers,” Rothwell wrote. “Opportunities for those with the least education are often in the metro area labour markets with the most education.”Pittsburgh has the most recession-resilient labour market, based on education gap, house price trends and industry growth, according to the study. Its greatest strength is in housing prices, which rose 7.3 percent since 2006, even as prices dropped by 15 percent in the average large metro area, the study said.The California metro areas of Sacramento, Riverside, Bakersfield, Stockton, Fresno and Modesto accounted for six of the 10 least resilient metro areas in the nation. The Miami-Fort Lauderdale-Pompano Beach region was least resilient.Education gaps pose a “longer-run challenge for many regional labour markets” because they account for about two- thirds of the variation in the level of unemployment across metro areas, Rothwell wrote.San Jose, located in Silicon Valley, where many of the world’s largest technology companies are based, had the highest level of demand for highly educated workers, according to the study.Some 56 percent of openings required at least a bachelor’s degree in the area, while only 36 percent of existing positions required such credentials, the study showed.Apple, based in San Jose’s neighbouring city of Cupertino, became the most valuable company in history this year, topping $633 billion as the shares soared 67 percent on demand for iPhones and iPads.The Valley also is home to Google, Intel, Cisco Systems and Hewlett-Packard.Fewer than one-third of openings in cities such as Cape Coral, Fla., and Youngstown, Ohio, required a bachelor’s degree, highlighting the variation among the largest cities.Occupations that had high demand for workers were also the ones that sought employees with more education, Rothwell said. Computer jobs, in which 63 percent of workers have at least a bachelor’s degree, were the most heavily advertised online, followed by health practitioners, a profession in which 71 percent have that level of education, the analysis showed.Higher educational attainment also benefits cities by making workers more employable and entrepreneurial, leading to more job openings for less-educated workers as new businesses hire, the report said.“Given that more than half of new jobs typically come from establishments started within five years, the lack of openings implies a need for more entrepreneurship,” Rothwell wrote.
