Stock Market Crash of 1929 - Many believe erroneously that the stock market crash that occurred on Black Tuesday, October 29, 1929 is one and the same with the Great Depression. In fact, it was one of the major causes that led to the Great Depression.
For the first two-thirds of the 20th century, Algeria’s high fertility rate caused its population to grow rapidly. However, about a decade after independence from France in 1962 the total fertility rate fell dramatically from 7 children per woman in the 1970s to about 2.4 in 2000, slowing Algeria’s population growth rate by the late 1980s. The lower fertility rate was mainly the result of women’s rising age at first marriage (virtually all Algerian children being born in wedlock) and to a lesser extent the wider use of contraceptives. Later marriages and a preference for smaller families are attributed to increases in women’s education and participation in the labor market; higher unemployment; and a shortage of housing forcing multiple generations to live together. The average woman’s age at first marriage increased from about 19 in the mid-1950s to 24 in the mid-1970s to 30.5 in the late 1990s.
