Travel Data & Forecasting

International Travel to Every US State 

International State Travel shows where international visitors to all 50 US states come from, what they spend, and where demand is heading, with origin-country detail and 10-year forecasts you can compare state against state. 

International Visitation, State by State 

International State Travel (IST) provides international travel data and forecasts for all 50 US states, broken down by country of origin. It tracks international visits and visitor spending by source market, with historical data from 2000 and forward-looking 10-year forecasts, so you can benchmark states and follow how global demand into the US is shifting. 

IST measures international travel into US states, the visitors arriving from other countries, not domestic travel between states. 

What you can do  

  • Compare states on international visits and spending, by origin country and region 
  • See which global markets drive demand to each state, and how that is changing 
  • Track international market performance over time, against history back to 2000 
  • Build custom views and export to Excel or maps

Synthesized Data, Consistent Across Every State

International State Travel triangulates several international arrival statistics, including survey data, origin-destination air passenger flows, and mobile location data. Those inputs are informed and constrained by national and regional totals, so individual state estimates stay consistent and comparable with one another. Forecasts then extend each series ten years out using the Oxford Economics Global Economic Model.

Where International Demand Meets State Strategy 

Benchmark Against Competitive States 

Measure international visits and spending against peer states to see where each one stands and where to focus.

Frequently Asked Questions

What is International State Travel?

International State Travel (IST) is a subscription service providing international travel data and forecasts for all 50 US states, broken down by country of origin. It covers international visits and visitor spending by source market, with historical data from 2000 and 10-year forecasts. 

Does IST cover domestic, state-to-state travel?

No. IST measures international travel into US states, meaning visitors arriving from other countries. It does not track domestic travel between states. For travel demand at the city level worldwide, see Global City Travel; for country-level travel globally, see the Global Travel Service. 

What is the difference between “international” and “overseas” visits?

International visits include arrivals from all source countries. Overseas visits exclude Canada and Mexico. IST provides both, so you can analyze total international demand or focus on overseas markets. 

Where does the data come from, and how often is it updated?

IST combines survey data, origin-destination air passenger flows, and mobile location data signals for each state and origin-country pair, constrained to national and regional totals for consistency, with forecasts built on the Oxford Economics global model. Historical data runs from 2000, and the service is updated quarterly. 

How does IST relate to the Global Travel Service and Global City Travel?

The Global Travel Service covers country-level travel worldwide, and Global City Travel covers travel for 300+ cities. International State Travel applies the same forward-looking approach to international travel into individual US states. The services are designed to work together for a holistic view of the global movement of travelers.
