Table 2 UK 2019 country-level estimates for proportional age demographics (%); includes full population (\(\:N\) = 12.64 million). Age group (AG) population estimate, per country, and associated proportional age group demographics both within ((\(\:N\)_{AG, country}/\(\:N\)_country)*100) and between countries ((\(\:N\)_{AG, country}/\(\:N\)_{total AG})*100). Example: 15.9% of England’s population is within the geriatric development period (‘within country’) and 83.3% of the UK geriatric population can be found within England (‘between countries’).
