Tel Aviv absorbed 42,000 immigrants from the FSU, many educated in scientific, technological, medical and mathematical fields. In this period, the number of engineers in the city doubled. Tel Aviv soon began to emerge as a global high-tech center. The construction of many skyscrapers and high-tech office buildings followed. In 1993, Tel Aviv was categorized as a world city.
