  Lagos - Over 30 Million People  POPULATION This case study of Nigeria, the country with the largest population in sub-Saharan Africa, builds on Global Demographics and Population Projections which illustrates the problems that African countries continue to have. Rapid population growth has made it difficult to deal with these problems in the past; continued large population growth in the future will be even more burdensome.  Nigeria became independent in 1960. Its population was 45 million people. In 2024 its population was 233 million people. Nigeria’s capital, Lagos, is already one of the largest cities in the world. In 2050 Nigeria's projected population will be in the range of 375-400 million people, depending on how fast its birth rate continues to come down. Around that year Nigeria will replace the United States as the third most populous country in the world.    By 2100, Nigeria is projected to have at least  700 million people , which will be abo...

    OVERVIEW Much of this is taken from the summary of the longer and more detailed Global Demographics and Population Projections This is a summary and overview of the demographics and population projection essays on this blog (links below). The world is at the beginning of a major shift in population, from large population increases since 1950 to decreasing populations in many countries and, in the long run, in the world as a whole. This historical shift in global and national populations will have a big influence on what happens in the future.   In summary, ·        Huge population increases since 1900, especially after 1950. ·        Because of a big decrease in birth rates in the world outside of Africa, starting with below-replacement birth rates in the 1970s, global population will increase until the 2060s and then start to decrease. ·       T here are, according to the United Nations , 63 countries w...

The Future Manufacturing Labor Force   SUMMARY This post is a summary of some of the themes of previous posts on demographic and population projections, with an emphasis on how demographics impact economic growth. See bibliography at the end of this post. For a list of all blog posts on a wide variety of topics, see  List of Posts by Topic   on my blog.   Two-thirds of countries are experiencing birth rates below replacement. Almost all countries outside of Africa have or will soon have below replacement birth rates. The latest countries that have below replacement birthrates are India, Bangladesh and the Philippines. Without immigration, this could lead first to smaller labor forces with greater numbers of retired citizens. Eventually, however, both the number of workers and retired citizens will decrease. During both stages of the transition, there will be issues of how to increase total output, maintain standards of living, and allocate income between the two majo...
