The EHS consists of:
- face-to-face interviews with a random sample of about 13,300 households a year
- a physical inspection of the homes of about 6,000 of the interviewed households – these are selected at random and carried out by a surveyor
The surveyor also inspects a random sample of about 200 properties identified by the interviewer as vacant.
Weighting is used to adjust the results of a survey to make them representative of the population.
For example, a survey which contains 25% females and 75% males will not accurately reflect the views of the general population, which we know is around 50% male and 50% female.
Statisticians rebalance or ‘weight’ the survey results to more accurately represent the general population. This helps to make them more reliable.
Survey weights are usually applied to make sure the survey sample has broadly the same gender, age, ethnic and geographic make up as the general population.
In the EHS, weighting makes the results more representative of the 22.6 million households in England.
Suppression rules and disclosure control
Estimates based on less than 30 households have not been included in these statistics, because small numbers of households make it impossible to draw meaningful conclusions. The analysis has been done by binary classification only where broken down by socio-economic group, income, region or age. This prevents small numbers appearing in the table and avoids the potential for identification of individuals.
More detailed data, including some potentially disclosive data, is protected by a range of disclosure controls. See the guidance on English Housing Survey: datasets for information accessing this data.
Estimates in the charts and tables are given to the nearest whole number. You can get more detailed estimates to 1 decimal place if you download the data.Quality and methodology information
