The object of this research was to determine the subjective recognized social threats in the context of contemporary society. Given the growing number of people who feel threatened by certain social threats, there is a presumption that the risk is real, and the identified groups are affected by social risks. The recognition of social threats in the population has a broader social context, and may be influenced by key socio-demographic factors. This influence is significant for many risks, and helps to better understand the nature of the specific groups at risk. It also allows us to recognize that the socio-demographic and family context creates specific conditions for the occurrence of social threats. The aim of the paper is to find the relationships between different types of social threats and gender, age groups, personal situation (occupation), educational attainment, and family situation. A similar study was carried out by the OECD in 2018 (the Czech Republic was not included). The research was designed as cross-sectional ex-post-facto, and the statistical significance was determined using χ2 test of independence. The survey was carried out in 2018–2019 nationwide across the Czech Republic. The processed data of 5425 respondents has shown that, in the Czech Republic, the subjectively perceived significant threats seem to be the loss of job and unemployment, insufficient skills, and an unwillingness to educate oneself or to be trained, social pressure, and unsatisfactory housing conditions. The research reveals that the recognition of social threats depends on social and family conditions, and there exist specific groups feeling threats more intensively than exist in others. The groups that are at the most risk are individuals with primary education and an apprenticeship. In the population, women are more at risk, as well as the 25–34 and 45+ age groups.
