In Switzerland, the crude birth rate in 1850 was thirty live births per thousand people, meaning that three percent of the population had been born in that year. In the second half of the nineteenth century, the crude birth rate of Switzerland fluctuated between 27 and 32 births per thousand people, before dropping from 28.5 in 1900, to fifteen in 1940. After the Second World War, Switzerland experienced a baby boom, and from the 1940s until the 1970s the rate rose above it's previous trajectory to between 17 and 19, before dropping sharply in the 1970s. From 1980 onwards, the crude birth rate of Switzerland has remained between ten and twelve births per thousand people, and it is expected to be just 10.3 in 2020.
