In the regions of Latvia there still exists a large unused resource – social capital (SC). Ineffectively implemented development policies, population’s alienation from the state democratic institutions, a low level of non-governmental engagement and SC, lack of resources in the local government sector, increased emigration, civic cynicism, low conditions of the prestige of the political profession have facilitated the development differences among territories. The research goal: comparison of the social capital of Zemgale region, towns and districts. Monographic analysis and method of synthesis, data statistical research methods – grouping, comparison, the processing and interpretation of statistical data – the method for analyzing aggregate indicators, was used in the article. The research discovers the SC at the micro-level – the collaboration and attitudes between citizens and the state as well as in-between the individuals themselves, along with the macro-level – interaction of social groups as a part of a network which helps create trust to local government bodies as well as the state. The study indicates that the development of the Zemgale region is impacted not only by such social capital factors as the population density in the districts (0.37), the number of population until the working age (0.55), but also by the factor education level of the deputies (2009-2013) between the districts (0.12), towns (0.41), and the whole region (0.14). This verified the assumption that higher education level implies higher social potential and more active social inclusion. The authors suggest the local-governments to devote increased funding to the NGOs as it is the most active form of social capital, thus ensuring a long-term development of such initiative groups.
