Available rates for modern local authorities:
- Population Density (Persons per Hectare)
- Rate of Population Change (% over previous 10 years)
- Percentage aged under 15
- Percentage aged 15-64
- Percentage Aged over 65
Firstly, population density: which areas had the most people? Density is calculated as the number of people per hectare, and we have measured areas from a modern digital map of the local authorities rather than relying on the doubtful acreages given in historical reports. Secondly, growth rates: where was population rising fastest, or declining? We also look at the ratio of men to women.
This theme also covers people's ages. From 1851 onwards, the census has provided very detailed statistics of age structure, giving numbers of males and of females in each 5-year age band. However, we simplify this here to three broad age groups: Children (0-14), Working Age (15-64) and the Elderly (over 65).
Over the last 150 years, Our population has clearly aged. However, mortality decline in the late 19th century was mainly due to the reduction of very high infant mortality rates: the presence or absence of large number of infants dying before their first birthday had little effect on overall age structures. During the twentieth century, declining fertility and improved life expectancy in later life significantly changed age structures.
These other rates are also available for this theme but cannot be mapped for modern units:
- Population Density (Persons per Acre) (by Administrative County in 1961)
- Population Density (Persons per Acre) (by Poor Law/Registration County in 1911)
- Population Density (Persons per Acre) (by Scottish County in 1951)
- Rate of Population Change (% over previous 20 years) (by Administrative County in 1951)
