Interactive visualisations for rates of use of the Mental Health Act for different groups of people and information on data quality.
Under the Mental Health Act, people with a mental disorder may be formally detained in hospital (or 'sectioned') in the interests of their own health or safety, or for the protection of other people. They can also be treated in the community but subject to recall to hospital for assessment and/or treatment under a Community Treatment Order (CTO).
People may also be placed under Short Term Detention Orders for mental health disorders by the police, and taken to a 'place of safety'. We report such uses where the place of safety was a hospital.
These statistics are derived from the Mental Health Services Data Set (MHSDS) which reuses operational data produced by NHS and independent providers. The data are known to be incomplete and are therefore an undercount at England level.
This report presents selected measures from the 2016-17 publications onwards alongside provider-level data quality information to help users understand the impact of local data quality issues.
Recorded uses of the Mental Health Act: crude rates per 100,000 population
This visualisation shows recorded uses of the Mental Health Act from 2016-17 to 2019-20, presented as crude rates per 100,000 population.
They allow you to compare rates of detention, uses of short term orders and uses of Community Treatment Orders (CTOs) between different age groups, ethnicities and genders.
This visualisation shows data for a particular type of short term detention order, known as a section 136 order, where the place of safety was a hospital.
Select a measure to display crude rates for that measure only. Select a reporting year to display crude rates for that year only.
Rates of detention are also shown by sustainability and transformation partnership (STP) area in the England map.

Data quality: Provider level coverage for key data tables
This visualisation shows the number or records received by NHS Digital in each of the key MHSDS tables used in the Mental Health Act Statistics publication between 2016-17 and 2019-20. Please note that there is no direct relationship between the number of records submitted in any one, or all, of these tables and the measures presented in this report, which are derived from a combination of these items. However, without records in these tables, these statistics cannot be produced. Table MHS101 is not directly used to produce these statistics but provides useful context about overall caseload.

Please note that CTO data successfully submitted by Lancashire Care NHS Foundation Trust was excluded from the published CTO statistics in the Mental Health Act Statistics in 2016-17, 2017-18 and 2018-19 due to data quality issues.

Information about the quality of Mental Health Act data in the MHSDS, including information by provider and data table.
What the report can't tell you
How many people were subject to the Mental Health Act, as the MHSDS data are known to be incomplete.
If variations by STP area are due to variations in levels of uses of the Mental Health Act or due to data quality limitations.
If changes in detentions or people detained at provider level are due to data quality issues or changes in service capacity or configuration. Local knowledge may be needed to accurately interpret these changes.
These statistics were produced from the Mental Health Services Data Set (MHSDS) for the first time in 2016/17, allowing new breakdowns to be produced for this subject. Find more information about the MHSDS.
Map boundaries are displayed by STP.
All values are rounded to the nearest 5, except values that are 4 or lower (including 0) which are suppressed to prevent the identification of individuals.
Figures produced by aggregation in this report may differ from those published as this report calculates totals as the sum of rounded figures.
Suppressed values appear as blank cells in tables and are not counted in rounded totals.
Percentages are based on pre-suppressed values and rounded to zero decimal places, except where the numerator is 0-4, where the percentage is suppressed.
