Goal and impact

If someone has received too much or unjustified assistance, this usually has to be repaid to the municipality. This is called recovery. We call the person who has to repay this amount 'debtor'.

The IB helps municipalities do this properly and carefully.

The algorithm allows municipalities to better assess whether someone can (partially) repay the social assistance debt, or whether, for example, a payment arrangement needs to be adjusted. It also helps in finding people who have dropped out of the picture after stopping benefits.

How does it work?

The municipality reports to the IB which residents have a debt related to welfare. The IB requests data from various sources about these people's income and/or assets. Based on this, the municipality then receives signals back.

For example, the municipality receives information about:

• whether someone has renewed (or structurally higher) income,
• whether there are assets or a bank balance,
• whether vehicles are registered (data from the RDW).

With this information, the municipality can determine what is a good next step.

Benefits at a glance:

Recovering assistance debts takes a lot of time and effort.

People in debt often have little money, and are sometimes hard to reach. This information service helps municipalities do the job faster and in a more targeted way.

• Municipalities can take steps faster, such as starting a wage garnishment.
• Staff can make better use of their time by receiving targeted signals.
• Municipalities can respond faster if something changes in a resident's situation.
• More and more collections can be made, because information is available earlier.
• Less money is needed for bailiffs, for example.

Considerations

The algorithm ensures that municipalities only receive information on residents with social assistance debt that they themselves provide. And only if something has changed that could affect the process of recovering that debt.

Thus, data is shared only when necessary. In doing so, we protect citizens' privacy. 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

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

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

The municipality decides whether and how to deal with a change.

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).

In addition, it can be specified whether vehicle ownership should be shown or not.
