Here is a collection and apps and software packages I have been involved in
With Gerko Vink and Rianne Schouten , we developed a procedure to create multivariate missing data. The idea is that this procedure can be used to for example generate missing data for simulation studies, or inform the design of a matrix-survey (also called modular design) questionnaire.

Statistics Netherland and Utrecht University are developing new ways to collect better social data, notably by using smartphone apps that can collect survey data, but also sensor data. For an overview of all projects, as well as source-code, please see https://gitlab.com/tabi/projects.
For outputs, please see the https://www.peterlugtig.com/publication/ page.
