Urbanization: Urban areas with a wealth of amenities and employment opportunities tend to come with a higher price tag for living. Why? Well, more people want to be there, which drives up home prices and rents. On the flip side, less densely populated rural areas or places where there's not as much demand usually mean fewer attractions, things to do and slower job growth. That often results in a lower cost of living.

Transportation: If public transportation is limited or not available, residents may need to own and maintain vehicles, which can add to the cost of living. Gas, insurance, regular maintenance and potentially lease or finance payments will all need to be paid on a monthly basis. In Mill Creek, the transportation index is 6.5% higher than the national average.

Housing: High demand for housing in desirable locations can drive up property prices and rental rates. This can be a primary contributor to a higher cost of living. While low demand for housing, especially in undesirable locations, can have the reverse effect and drive prices down, resulting in a lower cost of living. The housing index in Mill Creek, is 188% higher than the national average.
