During the period usually thought of as the first Demographic Transition in England (1870-1930) fertility fell faster than mortality and the population growth rate was slowing ... 3/4

Instead of following the classic Demographic Transition Model, in England very rapid population growth before the mid 19C was driven by rises in fertility as well as falls in mortality, and fertility contributed more than mortality did ... 2/4

... places with high fertility have low CO2 emissions, & few places have lowered fertility without massively increasing emissions. So 'population control' is unlikely to reduce environmental impacts on its own. Better to focus on reducing per capita consumption and waste where these are still high.

Campop blog #33: In the UK the infants of non-cohabiting parents are still at higher risk of infant death than those of cohabiting parents. This week's blog explores the historical trends and reasons for such disadvantage

In the pre-industrial period the seasonality of births reflected the agricultural working year, with fewer conceptions during harvest, and a peak of births in Feb-March. As first births were a relatively small proportion of overall births, it bore little relation to the seasonality of marriage 4/5
January 2, 2025 at 5:08 PM
The seasonality of marriage in the 16th-18th centuries was shaped by religious bans on marriage in Lent and other times of year, and because after the harvest work was over, workers were paid and released from a year's work. 2/5

The English Industrial Revolution (1750-1850) was characterised by substantial regional specialisation. Some areas specialised in industry but others de-industrialised during this period: Norfolk went from being the most industrial county to one of the least industrial. 3/3

The major increase in people working in the English industrial sector took place between 1550 and 1700. What happened in the Industrial Revolution was technological intensification: mechanisation raised efficiency, allowing output to increase without increases in labour. 2/3

... although average age of women at childbirth is the same now as in the 19th century, women have fewer children, so the average age at first birth is much higher now. 2/2

Campop blog #22: Queen Elizabeth II died of 'old age' - a rare cause today but common in the past. The history of this cause of death can tell us about changes in medical provision, medical knowledge and acceptable causes of death

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 population ageing
October 10, 2024 at 9:17 AM
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.

Unmarried mothers were predominantly not servant girls taken advantage of by their employer, but those whose marriages had been agreed but fallen through
October 3, 2024 at 11:16 AM
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
October 3, 2024 at 11:15 AM
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.

From my generation this difference is even larger: Margaret had 14 grandchildren, Moira had 6 and Kathleen 0: our grandmothers had an average of 5.2 children, nearly double the actual number of 2.7. 4/5
August 18, 2024 at 2:33 PM
In their children's generation, there are more people to remember coming from a big family (5 - see picture) than from a small (2), and no-one to remember a family size of 0. The average family size from the child's point of view is 4.9, far larger than the real number of 2.7. 3/5
August 18, 2024 at 2:32 PM
Here's my grandmother, Margaret, with her sisters and mother. The 3 girls went on to have an average of 2.7 children: Kathleen had none, Moira had 2 and Margaret had 6 (5 surviving to adulthood). What does this look like from their descendents' point of view? 2/5

Campop blog #5: Before women in Britain started to deliberately restrict their fertility in the late 19th century, they had an average of fewer than 5 births each. This blog explains why this number isn't higher www.campop.geog.cam.ac.uk/blog/2024/07...
