Land Registry

The data is usually released with a month delay (ie. properties sold in January are released at the end of February), with some records delayed for up to 3 months. That means if you want to see all sales for 2018, you need to wait until the end of March 2019. Price Paid Dataset is the most reliable open data source about the residential property sales and the biggest world public dataset about property sales. It includes over 23 million property sales in England and Wales since 1995. It’s approximately 1 million sales transaction per year.

Police data

includes over 43 million crime records since the beginning of 2011. It’s roughly 6 million committed crimes per year.

2011 Census data

From census 2011 we use postcode headcount and a workday population. Postcode headcounts are the only Census statistics that are available for full postcodes.

The workday population is collected for output areas. In some cases, these areas do not align with the postcode sector boundaries. In this situation, we approximate the total number of workday population. In most cases the approximate number is precise, nevertheless, for very small postcodes the error can be significant.

Comparing census data in 2001 and 2011, significant population change occurred in 2.6% (based on output areas units).
