Definition

Residents aged 0 to 15 as a percentage of total population, from the Office for National Statistics mid-year estimates for 30 June. United Kingdom regions and local authorities.

The ONS groups children as aged 0 to 15, the ages before the working age group of 16 to 64, so this share includes one more year of age than population_0_14_share (Eurostat and World Bank) and is a little higher. Published rounded to one decimal.
