Any arrangement done by older people for fund their later life, to be able to financially independent or secure can be a area related to public affairs. If not so, broadly what are the various categories or areas where we can put it.
Pension contributions for the aged basically come in different forms per the standing order of the new pension schemes available. if the aged was a worker in the public sector, then he would fall under the obligatory contribution category. also these same people can decide to make contrributions to private schemes which is more like a savings scheme. But if the aged find themselves in the informal, there is still a scheme available for them to make voluntary contributions towards old age. These groupings are in the Defined Contribution schemes.
