Social Security System of the Czech Population in the Context of Demographic Development

Today, sustainable development is seen as a balance between the three fundamental pillars: economic, environmental and social. Make the world a fair, liveable and viable, it needs a more comprehensive approach when deciding on the future development of human society. The use of demographic science knowledge can be very useful. Especially for the assessment of the status and possibilities of the social pillar, many of its analyses, theoretical and methodological knowledge can be used. Therefore, the article focuses on the process of aging of the Czech population and the impact of this trend on the social security system of the population. And all this in connection with the need and further development of social policy in the Czech Republic. In its broad scope, the basic focus is on the social security system. In its content framework, issues related primarily to the sustainability of financing of all the basic parts that we rank among benefits and support in social security are addressed. That is why the expenditure part of the state budget, managed by the Ministry of Labour and Social Affairs, comes to the fore. Preferably, an important link between demographic development is examined, focusing on population size changes and age composition. These changes then deal with possible impacts on the pension area and selected state social support benefits. The accuracy of the evaluation is based on the data quality of the Czech Statistical Office and two key ministries (Ministry of labour and social affairs and Ministry of finance).
