system in East Asian countries such as China, Hong Kong, and Taiwan, Britons of Chinese, Hong Kong, and Taiwanese descent rank within the top 5 in British as well as international scholastic mathematical and scientific aptitude tests and tend to score better in these subjects than the general population average. British Chinese remain rare among most Special Educational Needs types at the primary and secondary school level, except for Speech, Language and Communication needs, where first-generation Chinese pupils are greatly over-represented with the influx of first-generation immigrants coming from Mainland China, Taiwan, and Hong Kong. Employment First generation British citizens of Chinese backgrounds remain over-represented in self-employment, however, rates of self-employment fell between 1991 and 2001 as second generation British Chinese chose not to follow their parents into business and instead choose to find employment in the paid labor market. First and second-generation British Chinese men have one of the lowest unemployment rates in the nation, with an unemployment rate of 4.08% and 4.32% compared with slightly higher figures of 5% for White Irish (first and second generation). Vertical segregation is also apparent for men and women in the British Chinese community. British Chinese men are twice as likely to be working than White British men to be in professional jobs (27%, and 14% respectively). Chinese men have the third highest rate of employment in managerial jobs at 31%. This compares to 45% for Indian men, 35% for white men and 23% for Black Caribbeans. A colossal rate of diversity in British self-employment and entrepreneurship in the British Chinese Community has been considerably high. East Asian British groups (Chinese, Japanese, South Korean) and British South Asian groups (Indian, Bangladeshi, and Pakistani) typically have higher rates of self-employment than Whites, while Black groups (Black African and Black Caribbean) have lower rates. Self-employment rates in the British Chinese community is generally higher than the national average. For instance, White British had self-employment rates of 17% in 2001, but the British Chinese self-employment rate was 28%, the higher than the British Indian rate of 21%, British Pakistanis of 27%, and the highest overall among Britain's main ethnic groups. However, overall aggregate self-employment fell between the decade of 1991 to 2001 as the proportion of British Chinese with higher qualifications grew from 27% to 43% between the years of 1991 to 2006. 75% of male British Chinese entrepreneurs worked in the distribution, hotel, and
