From 1910, Chinese immigrants were required to pay a £30 deposit and pass a written test to demonstrate that they could write 50 words in three different languages. The restrictions on Chinese migrants were tightened even further in 1931, but relaxed again by 1947 due to lobbying by the Chinese consulate. The 1943 census showed 12,394 Chinese residing in Jamaica. These were divided into three categories by the census, namely "China-born" (2,818), "local-born" (4,061) and "Chinese coloured" (5,515), the latter referring to multiracial people of mixed African and Chinese descent. This made Chinese Jamaicans the second largest Chinese population in the Caribbean, behind Chinese Cubans. By 1963, the Chinese had a virtual monopoly on retail trade in Jamaica, controlling 90% of dry goods stores and 95% of supermarkets, along with extensive holdings in other sectors such as laundries and betting parlours.
