This is the most technically sophisticated model we've ever been involved in; indeed, we believe it to be one of the most complex microsimulation projects ever undertaken anywhere in the world. It uses British Household Panel Survey (BHPS) data to model demand for social care under many possible financing systems for up to 20 years. The projects are made either by ageing the households - increasing the ages of household members and applying estimated probabilities of major events such as retirement, worsening of health and eventually death, or by selectively reweighing the households to match population projections.
The model has an elegant user interface allowing Welsh Government officials to make and analyse their own simulations.
Below is a gallery of screenshots of the model in action.
