Reporting AOW recipients with AIO

The aim is to help the municipality understand which citizens may be entitled to special assistance, due to incomplete state pension benefits. The algorithm works like a postman, receiving a list of citizens from the SVB, splitting it up and delivering it. So that each municipality receives a list of its own citizens.

Responsible use

Goal and impact

Sometimes citizens have incomplete state pension benefits. They may be entitled to special assistance. But they sometimes do not know that. The municipality can inform them about this. But to do so, the municipality needs to know which citizens are concerned. That is why the Social Insurance Bank draws up a list of citizens who may be entitled to it. Bureau InformatieDiensten Nederland (BIDN) uses this algorithm to ensure that each municipality only receives data on its own residents and not on residents of other municipalities.

In principle, it is the responsibility of citizens themselves to apply for income assistance. But municipalities are encouraged to help vulnerable citizens. So this is in the citizen's interest.

Considerations

The 'Reporting AOW-ers with AIO' is part of the information service Samenloopsignalering (see algorithm 'Samenloopsignalering'). Only the specific points about the 'Reporting AOW-ers with AIO' are explained here.


The algorithm ensures that a municipality only receives the data of its own residents.


HHereby, we protect the privacy of citizens. An advantage of this algorithm is that it works much faster than when someone does it by hand. This saves a lot of time for municipal employees. Also, fewer mistakes are made this way.

Human intervention

With BIDN itself, this algorithm does not involve human intervention. The algorithm executes rules devised by humans and is not 'self-learning'.

However, BIDN does ensure that the processing process has been done properly.

The municipality can tell the citizen that they may be entitled to extra help. The municipality can also choose to grant this help automatically. The municipality makes the decision on this.

Risk management

Citizen privacy is a major concern. That is why we periodically check whether there are risks and what can be done about them. This is called privacy impact assessment (PIA).

Technical design

The source data contains a field with the municipality code. The algorithm splits the source file based on these municipality codes and divides it into a smaller file per municipality.


The generic services provided by the information service include:


Splitting a source file to be received monthly from SVB by municipality and delivering it to municipality based on a report in CSV.

  • Bureau InformatieDiensten Nederland (BIDN) receives lists of people on welfare benefits from municipalities and compares them with data from sources such as UWV, DUO and the Tax and Customs Administration. If there is any overlap (concurrence) that could affect the benefit, BIDN sends a message about this to the municipalities. The municipality can then carry out further checks.

  • An assistance recipient can only apply for assistance from the municipality where the resident is registered. For example, as a result of moving house, a person may receive assistance from several municipalities. Bureau InformatieDiensten Nederland (BIDN) informs the municipalities about this. The municipalities can then stop unlawful ongoing benefits.
