Texas Firm Highlights Struggle for Black Professionals HOUSTON - As a partner and chief diversity officer at Thompson & Knight, Pauline Higgins was not afraid to press the issue of hiring minorities at the 126-year-old Texas law firm. But when she left in 2008, she was replaced by an associate with less clout. Pauline Higgins pressed the issue of hiring more minorities at Thompson & Knight, but when she left in 2008, current and former partners say there was little change. Now, current and former partners say, the diversity committee meets less often, and the firm has fewer black lawyers than before. It is a trajectory familiar in many elite realms of American professional life, where, even as racial barriers continue to fall, progress for African-Americans over all has remained slow - and in some cases, appears to be stalling. "You don't want to be a diversity officer who only buys tables at events and seats people," Ms. Higgins said recently. It's about recruiting and inclusion and training and development, with substantive work assignments. Nearly a half-century after a Texan, President Lyndon B. Johnson, helped usher in the era of affirmative action, the Supreme Court is poised to rule as early as this week on whether the University of Texas can continue to consider race as one of many factors in its admissions policy. It is a case that could have a profound impact on race-based affirmative action programs across the nation and has reignited a discussion of how much progress minorities, African-Americans in particular, have made in integrating into some of the most sought-after professions, especially since the recession. Only a little more than 1 percent of the nation's Fortune 500 companies have black chief executives, although there are some prominent exceptions, like Kenneth Chenault of American Express and Ursula Burns of Xerox. At the nation's biggest companies, about 3.2 percent of senior executive positions are held by African-Americans, according to an estimate by the Executive Leadership Council, an organization of current and former African-American senior executives. While about 12 percent of the nation's working-age population is black, about 5 percent of physicians and dentists in the United States are black - a share that has not grown since 1990, according to an analysis of census data that was prepared for The New York Times by sociologists at Queens College of the City University of New York. The analysis found that 3 percent of American architects are black, another field where the share has not increased in more than two decades. The share of the nation's lawyers who are minorities and women, which had been growing slowly but steadily for years, fell in 2010 for the first time since NALP, the National Association for Law Placement, began keeping statistics in 1993. The deep recession not only disproportionately hurt African-Americans in many fields, but it also led businesses to make diversity programs less of a priority. And a growing number of states - including Arizona, Michigan, Nebraska, New Hampshire and Oklahoma - have moved to ban race-based affirmative action in recent years. California, Florida and Washington did so in the 1990s. Such numbers raise the question of whether the private sector's commitment to affirmative action and diversity programs is eroding, even as the Supreme Court once again considers another high-profile case involving a public university. "We're at a precipice," said John Page, the president of the National Bar Association, an 88-year-old group representing black lawyers and judges. There is diversity fatigue. We could fall backwards very quickly. Even more worrisome to some people than the small number of African-Americans at the upper echelons of many organizations is a lack of progress at entry levels. In Texas legal circles, there have been some notable symbolic gains for black lawyers at the top of the profession; both the State Bar of Texas and the Houston Bar Association just elected their first black presidents. But many black lawyers said they worried that there were fewer young black lawyers in the pipeline for future leadership roles. While blacks made up only 2.65 percent of the partners at Houston firms in 2012, that figure represents progress as the share of black partners more than doubled over the past decade, according to statistics kept by NALP, the law placement association. At the lower levels of firms, black lawyers have lost some ground, however. Last year, Houston firms reported 4.74 percent of their associates as being black, down from 4.96 percent in 2002, the association said. Lisa Tatum, the black lawyer who will take over the presidency of the Texas bar next month, said there was concern that firms were not pursuing diversity as aggressively as they did before.
