FRED recently added World Development Indicators data on life expectancy at birth, which are from the World Bank. The graph above includes some of the available data. The green line shows that life expectancy has been steadily increasing in the world, but that the experience varies across countries. Consider the three large countries shown in the graph: the U.S., China, and Russia. Life expectancy in the U.S. has also been steadily increasing, but not that fast, likely because it was already high to begin with. China had a big surge in the 1960s. The Russian experience has definitely been rocky, with several decreases at several points.
How this graph was created: Search for “life expectancy,” choose the countries you’re interested in, and add them to the graph. There are several pages of listings, so you may need to add some from the graph page itself.
