Saudi Arabia counted 20,485 U.S. nationals in its 2022 census, 11,866 men and 8,619 women, at a reference date of May 10, 2022. It is close to the only hard number the Gulf publishes on Americans.
Across the six Gulf states, the agencies that log foreign residents by nationality for visa and security work almost never release what they hold, and the U.S. population, corporate, oil-and-gas and military, drops into an "Other" line.
This is not a capacity problem. Every one of these states runs an administration that enumerates foreigners by nationality internally. The gap is between what they record and what they release. Call it a data wall: administrative capacity that exists and produces non-publication.
The wall is a choice, not a gap
The distinction matters because it separates two different failures. One is a country that can't disaggregate by nationality. The other is a country that can and won't. The Gulf is the concentrated case of the second.
Kuwait's Public Authority of Manpower, the Royal Oman Police's Directorate General of Passports and Residence and the Federal Authority for Identity, Citizenship, Customs and Port Security in the United Arab Emirates each enumerate foreign nationals in detail. None publishes at that detail.
What reaches the public is a top-five or top-10 list of source countries, led by the Asian and Arab labor-sending states: India, Pakistan, Bangladesh, the Philippines, Egypt, Jordan. The United States sits below the cutoff.
The U.S. corporate, energy and military presence in the Gulf, plausibly 50,000 to 80,000 people across Bahrain, Kuwait, Oman, the UAE and Saudi Arabia, isn't enumerated in any host-country dataset AER could locate, apart from one Saudi census line.
Bahrain publishes nothing on Americans
Bahrain is the floor. It carries an AER Data Transparency score of 0.0, a blank across all five kinds of official publication the index checks: resident population, migration flows, naturalizations and work permits, none broken out for U.S. nationals. The nearest proxy is the 2020 census "North American" group, 16,415 people, which folds Americans and Canadians together.
The irony sits offshore. The largest concentration of U.S. nationals on Bahraini soil is the Navy. U.S. Naval Forces Central Command and the Fifth Fleet in Manama anchor a military and dependent population that U.S.-side sources put near 9,000. Bahrain's Labour Market Regulatory Authority, whose quarterly reports carry the only nationality detail the country publishes, lists the top 20 worker nationalities and the top 10 for dependents.
The United States appears on neither. That naval population sits on Bahraini territory under a status-of-forces arrangement, outside the labor authority's scope, and the civilian remainder folds into "Other."
Kuwait has the register but not the row
Kuwait runs the most developed population register in the Gulf. The Public Authority for Civil Information's continuous Civil Information Register reported a total population of 5,098,539 as of June 30, 2025.
The Central Statistical Bureau breaks residency down by article of the residency law against eight nationality groups, one of which is "North American Countries," a U.S.-and-Canada aggregate. Only the bureau's tourism bulletin gives the United States its own row. The Interior Ministry, which runs permits and naturalization, publishes no aggregate statistics at all.
So the data exists at high resolution and publishes at low resolution. On the AER index Kuwait scores 1.0 for U.S.-born data and 1.5 for U.S.-citizen data, not because the apparatus is thin but because it doesn't release what it holds.
What stopped the UAE from publishing?
The UAE went dark around 2010. No federal authority has published population, residency or labor-force data with a nationality breakdown since. The last federal census to give national and non-national totals ran in 2005, at 825,495 nationals and 3,280,932 non-nationals.
The Federal Competitiveness and Statistics Centre now reports population by gender only. The Federal Authority for Identity, Citizenship, Customs and Port Security publishes biannual "transaction" totals for permits and entries with no nationality split.
The most recent federal dataset with any nationality detail is a births series that ends in 2019. No U.S.-national residence figure exists from any UAE federal source.
Saudi Arabia is the exception that proves the point
Saudi Arabia shows the wall is policy, because it stepped over the wall once. Its 2022 census was the first to publish detailed non-Saudi population by country of citizenship, including the 20,485 U.S. line, the largest documented U.S.-citizen count among the Gulf states in this research.
The U.S. group skews male at 58%, though less sharply than the non-Saudi population overall, which runs 76% male.
Around that one release, the picture thins again. Ministry-derived workforce data show 6,882 U.S. workers in 2020, 6,127 in 2021 and 6,141 in 2022, with no later nationality series found; post-census estimates revert to a Saudi and non-Saudi binary.
Tourism is the one flow the kingdom reports at U.S. resolution, and it climbed from 61,100 arrivals in 2021 to 227,000 in 2022, 331,000 in 2023 and 388,000 in 2024. Those are visitors, not residents.
Why the wall is policy, not capacity
GCC-Stat, the statistical arm of the Gulf Cooperation Council, harmonizes data across all six states and still reports on a national and non-national binary or by region. It doesn't add source-country detail the members don't already publish. Every state in the bloc holds nationality-level data internally for visa or security use and declines to release it at that level. The non-publication is a decision.
Decisions can be petitioned. AER's records-request program targets the countries where the gap between what is enumerated and what is disseminated is widest.
The first full return came from Guatemala, not the Gulf, but it made the point. A records request resolved in four working days produced a complete year-by-year, visa-category count of U.S. nationals holding valid residency. A wall built on non-publication rather than non-collection has a door.
