Document Summary
Problem set 1: population pyramid, (see attached page for population pyramids and sources. , consider the changes in each country"s pyramids over time. Angola: both pyramids are characteristic of population pyramids of less developed countries, widening out at the base, which indicates that young people are a very large share of the population. A population can become older as a whole if fertility is decreasing or because mortality has decreased, leading to the survival effect . The change in shape suggests than a decrease in fertility rates is likely in angola between 1970 and 2012. Brazil: the 2012 population pyramid is characteristic of a developed country, while the 1970 pyramid suggests that brazil was a less developed country at the time. The population as a whole was much younger in 1970 (young people/children made up a larger share of the population). In 2012, the pyramid is rounder and the population has aged.
