The dependency ratio (ratio of older people and children to working age people) is also driven by fertility. In England it was lowest in 1671 (low fertility and high early age mortality), and peaked in 1826. Since then lower fertility has counteracted the effects of ageing

Until recently, population ageing was driven by fertility (determining the size of different generations) not mortality. Older people were relatively more common in the late 17th century when fertility was low, and less common in the 19th when fertility was high.

The blog also explains the ‘courtship intensity hypothesis’ and how it relates to sex before marriage, which caused me an interesting moment with @evanhd on @BBCPM in July.

Unmarried mothers were predominantly not servant girls taken advantage of by their employer, but those whose marriages had been agreed but fallen through

Over most of English history, less than 10% of births were born outside marriage, but in many periods over half of all first-born children were conceived before marriage

Interestingly, historical regionality is mirrored in much more recent times using data from telephone calls.

Overall women were more likely to die from other causes, but once pregnant, the risk of childbirth was inescapable & highly concentrated in time: in the 6 weeks after birth a woman faced 6 times her normal mortality risk: fear of death during childbirth was very understandable.

In pre-industrial England, the risk of a woman dying in or following childbirth was similar to the chance of dying from a non-maternal cause over the course of a year. Women did not give birth every year, so only 1 in 10 deaths to married women aged 15-49 was due to childbirth.

At its highest (mid-17th century) the risk of maternal death was 1.7% per birth event, and overall 5.6% of married women died during childbirth. Correspondingly, 94% of married women never died of childbirth, despite repeated exposure to the risk.

Campop blog #13: In 2021 only 7.6% of people in E&W walked to work and around half travelled by car - a massive change from modes of travel in the pre-1800 era, which are explained by Alan Rosevear in this week's blog.@CamUniCampop .

Many people think women entered the paid workforce in significant numbers only after WW1 & WW2. Amy Erickson explains why that's wrong in this @CamUniCampop blog @CamEcSocHist.
