Botswana has experienced one of the most rapid declines in fertility in Sub-Saharan Africa. The total fertility rate fell from more than 5 children per woman in the mid 1980s to approximately 2.4 in 2013, and remains at that level in 2022. The fertility reduction has been attributed to a host of factors, including higher educational attainment among women, greater participation of women in the workforce, increased contraceptive use, later first births, and a strong national family planning program. Botswana was making significant progress in several health indicators, including life expectancy and infant and child mortality rates, until being devastated by the HIV/AIDs epidemic in the 1990s.

In 2021,  Botswana had one of the highest HIV/AIDS prevalence rates in the world at close to 20%, however comprehensive and effective treatment programs have reduced HIV/AIDS-related deaths. The combination of declining fertility and increasing mortality rates because of HIV/AIDS is slowing the population aging process, with a narrowing of the youngest age groups and little expansion of the oldest age groups. Nevertheless, having the bulk of its population (about 60% as of 2022) of working age will only yield economic benefits if the labor force is healthy, educated, and productively employed.

Batswana have been working as contract miners in South Africa since the 19th century. Although Botswana’s economy improved shortly after independence in 1966 with the discovery of diamonds and other minerals, its lingering high poverty rate and lack of job opportunities continued to push workers to seek mining work in southern African countries. In the early 1970s, about a third of Botswana’s male labor force worked in South Africa (lesser numbers went to Namibia and Zimbabwe). Not until the 1980s and 1990s, when South African mining companies had reduced their recruitment of foreign workers and Botswana’s economic prospects had improved, were Batswana increasingly able to find job opportunities at home.

Most Batswana prefer life in their home country and choose cross-border migration on a temporary basis only for work, shopping, visiting family, or tourism. Since the 1970s, Botswana has pursued an open migration policy enabling it to recruit thousands of foreign workers to fill skilled labor shortages. In the late 1990s, Botswana’s prosperity and political stability attracted not only skilled workers but small numbers of refugees from neighboring Angola, Namibia, and Zimbabwe.
