Meal Prices: BTN rebuilt its meal and restaurant database in 2023. BTN will update meal data annually, using the following methodology.

U.S. Meal Data: Cities with annual GDP above $95 billion: BTN surveyed six independent restaurants and three hotel restaurants for breakfast; six chain and six independent restaurants for each lunch and dinner. For smaller cities, BTN surveyed two independent restaurants and one hotel restaurant for breakfast and three chain and three independent restaurants for each lunch and dinner. Breakfast based on an egg entree with fruit and coffee or juice. Lunch is an entree-style salad or sandwich, pizza, burrito, etc. with fruit; fries or chips; and nonalcoholic beverage. Dinner is protein-based entree; small salad; cheese tray or dessert; glass of wine. Sample breakfast restaurants include Denny’s, IHOP and Starbucks. Lunch chains include Chili's, Panera and Bonefish Grill. Dinner chains include Cheesecake Factory and Capital Grille.

Non-U.S.Meal Data: Breakfast based on continental breakfast. For lunch and dinner in each city that has a population of 1.5 million or more, BTN surveyed 12 restaurants; six in each smaller city. BTN converted prices from local currency to U.S. dollars on January 25, 2023. Lunch is based on a sandwich, salad and nonalcoholic drink. Dinner is based on a fish, chicken or beef entree; salad; a dessert or cheese tray; glass of wine.

Taxi Rates: BTN compiles taxi rate data annually primarily using Rome2Rio, but supported by additional sites for certain cities or locations.

Risk Scores: BTN uses GeoSafeScores powered by GeoSure. Scores incorporate structured and unstructured data from sources like the United Nations, Centers for Disease Control and Prevention, World Health Organization, Interpol, The World Bank, FBI and the U.S. State Department, as well as macro sources like inflation trends, education, income levels, political stability, trending health and disease data, neighborhood-level police presences, healthcare facility proliferation and infrastructure characteristics. BTN updates risk data quarterly.
