Open Postcode Geo is a postcode dataset and API optimised for geocoding applications. You can use Open Postcode Geo to geocode a dataset, geocode user input, and therefore build a proximity search. Data is derived from the ONS (Office for National Statistics) postcode database and is free to use, subject to including attributions to ONS, OS (Ordnance Survey) and Royal Mail. Information is provided on a range of topics, including education, health, crime, business, etc. Postcodes can be entered at area, district, sector, and unit level - see Postcode map for the geographical relationship between these.

De Locatie bij Postcode huisnummer API bevat gegevens over de locatie van adressen, bouwblokken, gebieden, kadastrale object, Kadastraal subject, Openbare Ruimte en postcode op City data.

This dataset classifies households by whether members identify as having the same or different ethnic groups. If multiple ethnic groups are present, this identifies whether they differ between generations or partnerships within the household.

Multiple ethnic groups in household are split into 6 categories including total.

The estimates are as at Census Day, 21 March 2021.

Dataset to hold Locality Lookup tables

This method returns total crime rates, crime rates by crime types, area ratings by total crime, and area ratings by crime type for small areas (Lower Layer Super Output Areas, or LSOAs) and Local Authority Districts (LADs). The results are determined by the inclusion of the submitted postcode/coordinates/UPRN within the corresponding LSOA or LAD.

All figures are annual (for the last 12 months).

The crime rates are calculated per 1,000 resident population derived from the census 2021.

The dataset is updated on a monthly basis, with a 3-month lag between the current date and the most recent data.
