The demographic crisis is a problem faced by the authorities of all EU countries and a number of countries in the world. Therefore, in many spheres of social and economic life it is necessary to implement innovative solutions and services supporting the functioning and development of ageing societies and responding to ever newer needs and expectations. In recent years, new technologies and the spread of the Internet have played a major role in the modernisation of services. It seems interesting to see how the rapidly developing computerisation helps modern communities to function. The aim of the article is to present public e-services in Poland that help to combat the demographic crisis. Special analyses were given to e-services in the area of social security, including social insurance, health insurance and family policy.
