What the data measures

The data shows the percentage of 5 year old children with signs of visible tooth decay, by ethnicity.

The results are based on a survey taken during the 2018 to 2019 school year where trained dental examiners did visual-only examinations to look for signs of tooth decay.

The data only includes children at mainstream state-funded primary schools.

Percentages are rounded to 1 decimal place.

The ethnic categories used in this data

Data is shown for 5 aggregated ethnic groups:

  • Asian
  • Black
  • Mixed
  • White
  • Other

This means estimates are shown for these groups as a whole. This is because the number of people surveyed was too small to make any reliable conclusions about any of the 18 ethnic groups.

Ethnicity was not known for 7.3% of 5 year olds. Children whose ethnicity was not known are included in the figures for ‘All’ in the data.

Methodology

Data for children from the Chinese ethnic group is no longer shown separately – it is now included in the ‘Asian’ ethnic group. Because of this, the latest data is not comparable with data from previous years.
