Estimated percentage of the population covered by the data source in the catchment area

On 2025-01-01 The Netherlands had about 18.000.000 million citizens and in IPCI we had 1.305.509 active patients. That means the coverage is 7,25 %.

Description of the population covered by the data source in the catchment area whose data are not collected (e.g., people who are registered only for private care)

GP practices included in the IPCI database are mainly located in the central part of the country, including the most
densely populated area (the ‘Randstad’) but also non-urban
areas. The IPCI database is a dynamic database in which
patients are included from their registration at the GP practice until death or leaving the practice.
