"longDescription": "CostLiving gives monthly cost-of-living estimates for all 50 US states, Puerto Rico and 244 US cities.\n\nAsk what it costs to live somewhere and you get a monthly total with the main parts broken out: housing, food and transport. Figures come in four tiers (budget, moderate, comfortable and luxury) and assume a single person renting a one-bedroom home unless you ask about a couple.\n\nYou can:\n- look up the monthly cost of living for a US state or city\n- compare two to five places side by side, with the percentage difference\n- rank states, cities, or cities within one state from cheapest to most expensive, optionally under a monthly budget\n- see the take-home (after-tax) income needed to cover living costs, for a single person or a couple\n\nEvery answer links to the CostLiving page the figure comes from, where the sources and method are explained. Figures are estimates for planning, not quotes. The app covers the US only; for places it does not cover it says so rather than guessing.",
