After all, how much it costs to live somewhere can be a huge factor in your decision. Affordability can be broken down into 3 common categories.

Urbanization: Larger, urban centers, known for their wealth of amenities and strong employment prospects, often exhibit an elevated cost of living, primarily attributable to the heightened demand for services and residential relocation. Consequently, this scenario leads to elevated home prices and higher rental rates. In contrast, sparsely populated rural areas or regions characterized by diminished demand typically provide a more limited array of amenities and experience slower job market growth, resulting in a more affordable cost of living.
Taxes: Areas with higher taxes, including sales taxes and income taxes, can contribute to a higher cost of living. Paying more tax for everyday household expenses like clothing and food will result in higher costs, as will paying a higher rate of income tax. The general sales tax rate in St. Marys starts at 4% and the income tax rates start at 1%.
Healthcare: Healthcare expenditures and insurance premium rates can vary significantly, contingent upon the particular city or state. Factors such as the accessibility of healthcare facilities, out-of-pocket expenses for doctor's appointments, dental care charges, prescription medication costs, and expenses related to specialized medical care can all have an impact on the overall cost of living. In St. Marys, healthcare costs are 6.9% higher than the national average.
