Introduction Geographic and demographic information about a selected group of vulnerable populations is an important aspect of developing strategies for the issue’s solution. Features of the demographic context promote developing accurate implementations for specific categories of the population. Geographic data contributes to the territorial analysis of the selected issue, which will lead to a more effective resolution strategy. It is formulated by the fact that territorial visualization helps to identify locations with the most problematic indicators. In turn, it will facilitate the leadership to develop a method to settle the problem depending on the specific conditions. Demographic information about the current vulnerable group of the population, namely the uninsured people, includes many indicators. It involves the number of the selected area population and the number of insured and uninsured individuals. Furthermore, for complete visualization of the issue, it is necessary to analyze the correlation of racial, ethnic, and gender indicators. This approach will help to identify patterns in demographic aspects, which also contributes to a more efficient solution to the problem due to more precise data. The selected location is Kings County (Brooklyn), which is the most populated borough in New York City. There were 2,73 million residents as of 2020 year (US Census Bureau). 7.2 % of the population under the age of 65 years do not have health insurance (US Census Bureau). Thus, a significant number of the population do not have adequate access to the essential part of services, namely health care. It is also worth noting that the COVID-19 pandemic negatively affected the indicators. 17,8 % of the population of Kings County, New York, are in poverty (US Census Bureau). As mentioned above, financial hardship is the most common reason for not having health insurance. The impact of the pandemic can be explained by the fact that many people have lost their jobs due to quarantine, which has led to the inability to obtain adequate insurance. Further, one needs to consider the number of the population without insurance in the context of gender. The percentage of uninsured men and women is almost equal, with 53 % of men and 47 % of women without health insurance coverage (US Census Bureau). As for regions, one may notice that the southern region of Kings County has the greatest percentage of the uninsured population at 52 % (US Census Bureau). The other regions include the Northeast with 13 %, Midwest with 19 %, and West area with 16 % of uninsured people (US Census Bureau). Ethnic indicators are formulated by the number of populace, namely European Americans having the greatest indicator of uninsured with 63 %, as it is the biggest part of the population in the county (US Census Bureau). Thereby, based on this data, one has the opportunity to accurately develop a methodology for solving the problem. Such data contribute to more effective addressing of the issue since one can develop directions that are necessary to be reinforced. Specific areas in which the most uninsured population are identified, thereby, all implementations must be applied on this territory in the first place. Moreover, it can serve as an indicator of the im
