Demographic Trends and Problems of the Modern World

Professor David Coleman gives the second lecture on Demographics, where he looks at different ways in which governments and demographers have collected population data.

Professor David Coleman gives the first lecture in his Demographic Trends and Problems of the Modern World series. He describes the challenges such as of a world population of 7 billion and how demographers are tackling these challenges.

There are many examples, from the ancient world to Nazi Germany, of attempts to protect or to increase the birth rate and hence population size. Slides to accompany Prof David Coleman's talk on birth control from governments. Few can be shown to be successful. France, since 1939, is an exception. The Nazi example put population awareness off the agenda in the West but the persistence of low fertility, with the population ageing which it causes have brought population concerns to the fore in...

Fear of population decline has haunted states ever since states existed. Population size was the basis of the power, security and prosperity of any political entity. Slides to accompany Professor David Coleman's on the fear of population decline. The great disparity of economic and military power between the West and the Rest from the 18th century temporarily put population size into the shade. As that advantage ebbs, population size has emerged once again as a major factor in international...

Traditionally, high birth rates were high. But as they were balanced by high death rates, population growth rates were usually very low. Prof David Coleman looks at family planning in the developing world. Rapid decline in death rates in the non-European world began after the 1940s. As birth rates generally remained high, that provoked an increase in population unprecedented in history - with a billion people being added to world population every 13 years by the 1970s. Some defended the...

Fertility in all but 12 countries in the world is now falling. Where will it stop? In this talk, Prof David Coleman looks at the demographic transition in the developing world. Conventionally the demographic transition was expected to end when birth rates reached replacement level. That has not happened. Birth rates in the developed world are mostly below it, some markedly so. What will happen in the developing world? Some populations have been very slow to begin the fertility decline, a...

Professor David Coleman from Dept of Social Policy, University of Oxford, gives a talk from his "Demographic Trends and Problems of the Modern World" series talking about the 'Second Demographic Transition'. The early 20th century was a time of very low divorce rates and of births outside marriage. Couples married late and many never married. In Western Europe, and the English-speaking world, all that changed after the 1960s; Cohabitation, divorce, births outside marriage made families much...
