This video from OMG revision looks at the different social and economic development indicators that can be used to measure a countries development and their level of social and economic well-being. There are a large range of development indicators, however, for the AQA specification you need to understand GNI per capital, birth rate, death rate, infant mortality rate, doctors per thousand people and access to clean water. Using one development indicator however has some data is hard to collect or some countries may simply lie about their level of development to appear more developed. A better way of measuring development is buy using a composite indicator such as the Human Development Index (HDI). The HDI uses three indicators (GNI per capita, Literacy Rate and Life Expectancy) and gives a country a score between 0-1; the closer a country is to 1 the higher its development. To revise this topic, you can research some countries and begin to think about the reasons behind their development indicators. For example, why have LICs like Afghanistan got high birth rates? Or why do HICs such as Japan have increasing death rates? Finally, it is worth learning some of the key indicators for the countries that we study in this GCSE such as the UK, Nigeria and Brazil.
