2. Things you need to know
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
Read the detailed methodology document (PDF opens in a new window or tab) for the data on this page.
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.
