Ken je Buurt is a Dutch information platform that helps people explore official data about neighbourhoods, streets, postcodes and addresses across the Netherlands. It covers all 342 municipalities and draws on open data from the Kadaster, including the BAG, and the CBS, alongside geospatial information from PDOK. The site provides facts on property values (WOZ), safety, schools and energy, with address and postcode information available down to house-number level.

Its tools include an interactive postcode map showing average building age, postcode-level elevation relative to NAP, flood-risk information, groundwater and soil data, and cadastral parcel details such as registered area. Ken je Buurt also publishes data-led comparisons and rankings, including neighbourhoods and postcodes with high average WOZ values, municipal home-sale prices, housing-price changes and population density, as well as areas with high shares of homes without natural gas. The research is presented with transparent selection criteria and links to the relevant locations. The platform is designed to make public data accessible for local exploration and comparison.
