In 1966, Japan experienced a sudden drop in its fertility rate—for just that year. During the 1960s, the fertility rate was about 2.0 to 2.1 children per woman, but in 1966 it dropped dramatically to 1.6 children per woman (Chart 2). The number of births in 1966 was much lower than in surrounding years, as can also be seen in Japan’s population pyramid, where there’s a big dent for people born in 1966 (the highlighted bars). This isn’t an error in the data, it’s real.
Every minute, dozens of people in East Asia move from the countryside to the city.
The massive population shift is creating some of the world’s biggest mega-cities including Tokyo, Shanghai, Jakarta, Seoul and Manila, as well as hundreds of medium and smaller urban areas.
This transformation touches on every aspect of life and livelihoods, from access to clean water to high-speed trains that transport millions of people in and out of cities during rush hour each weekday.
