This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 13th (it will be out in January 2020), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.

You can download an iPhone app for the 13th edition from the App Store (search for Weeks Population).

Brazil Has Shifted Rather Dramatically to an Aging Population

Thanks to Duane Miller for linking me to a very interesting story on WorldCrunch about the way in which Brazil has quite dramatically become an aging population. This is a very predictable consequence of a rapid increase in life expectancy accompanied by a rapid decline in fertility--one that has sent birth rates below replacement level. 
While demographic trends indicate an aging population worldwide, Brazil's rate is outstanding for its speed. Countries like France, the United Kingdom and Spain, which are already known for their inhabitants' longevity, needed three times as long as Brazil to double their percentage of older population. By 2040, older people are expected to constitute one-fifth of Brazil's population, up from 10% in 2010.
Among traditional reasons given for demographic changes (fertility, mortality, migration, wars, epidemics), it is the basic fall in fertility rates and rise in life expectancy that best explain the widening of the Brazilian population pyramid. The number of children per woman has dropped significantly in recent years. In 2015 the figure was 1.7, which is considerably less than the average number of children for grandmothers two generations earlier (6.3 per woman).
Now, to be sure, the dramatic drop in fertility in Brazil has been known about for some time. I blogged about it back in 2011, for example. But, it takes any society some time to adjust to the reality of this dramatic demographic shift, and Brazil has had a variety of political and economic crises that tend to drain national attention away from the less obvious, even if dramatic, demographic trends taking place.
The demographic change is among the biggest challenges of modern Brazilian history, alongside such phenomena as accelerated urbanization and the push for universal healthcare and education. The challenge is multiplied by the fact that no government targets can alter its progression. The country needs to design appropriate public policies and create institutions and infrastructures to meet the needs of a growing number of "grandparents" populating the country's cities and countryside. These are long-term challenges that require a serious and rapid response from both the political class and society as a whole.
Every society undergoing a rapid decline in fertility needs to know these things, but most seem to ignore them until the demographic transition becomes the demographic crisis.
