When asked to estimate the total size of their target market, expatriate marketers often face difficulties with the answer. There’s virtually no clean global dataset on “expatriation” as a commercial segment, and the available statistics usually do not differentiate between migrants, international students, seasonal workers and high-income professionals. So what can you say the next time your leadership team asks where to spend the expatriate marketing budget?

According to UN DESA international migrant stock figures, well over 280 million people live outside their country of birth in recent reference years: up from roughly 215 million a decade earlier in earlier UN waves. That headline number is useful for context, but it is not a ready-made addressable market. An offshore bank is probably not looking to attract foreign construction workers in the Middle East, and an international health insurer will not be focusing on people who settled in the United States twenty years ago and now behave like local consumers.

The practical task for B2B marketers is to segment that global stock into commercially relevant cohorts: newly arrived skilled professionals, corporate assignees, internationally mobile self-employed people, retirees with portable wealth, and high-earning diaspora communities who still buy cross-border products.

Why “expat market size” is hard to pin down

Three definitional problems sit behind every spreadsheet argument:

  1. Legal status versus lifestyle. A work visa, permanent residency and dual citizenship can describe people with very different media habits and product needs.
  2. Income and spend. Aggregate migrant stock includes low-wage labour migration. Most expat-service categories (international private medical insurance, premium banking, international schools, relocation) care about the upper end of the income distribution.
  3. Length of stay. First-year arrivals behave differently from long-term residents. Many acquisition campaigns should weight inflows as heavily as stock.

UN migrant stock, OECD permanent and temporary migration series, national census foreign-born counts, and commercial panels such as HSBC’s Expat Explorer or InterNations’ Expat Insider all answer slightly different questions. Treat them as complementary lenses, not interchangeable totals.

How many high-income expats are there?

Despite the rapid development of large emerging economies, the traditional migrant destinations of the United States, the United Kingdom, Canada, Australia and parts of Western Europe still host large populations of highly skilled foreigners. Countries and regions that have grown quickly in total migrant population, including parts of the Middle East and South Asia’s outbound corridors: do not always convert that volume into the same density of high-income, English-speaking (or multilingual) consumers that insurers, banks and schools typically chase.

Besides foreign-born stock, the yearly influx of migrants is a critical planning input. New arrivals look for banking, insurance, telecoms, housing, schooling and professional services in a compressed window: often the first three to twelve months after landing.

Among OECD countries, the United States and the United Kingdom have long ranked near the top for skilled and overall arrivals, with Germany, Canada and Australia also featuring prominently depending on the year and visa category. Germany’s annual inflows have frequently exceeded half a million people in recent high-migration years, which matters if your product attaches to relocation moments rather than long-settled communities.

Illustrative planning view: stock versus inflow

The table below is illustrative for campaign planning conversations. It is not an official statistic; it shows how a marketer might think about the difference between total foreign-born presence and commercially hot inflows.

Destination clusterPlanning emphasisWhy it matters for budget
US, UK, Canada, AustraliaLarge skilled stock + steady inflowsBroad media options; high competition for attention
Germany, Netherlands, NordicsStrong temporary and skilled inflowsLanguage localisation and employer-channel partnerships
UAE, Singapore, Hong KongHigh density of mobile professionalsShort tenure cycles; premium product affinity
Spain, Portugal, ThailandLifestyle / retiree + remote-work mixLonger consideration cycles; different creative tone

Use national statistical offices and OECD International Migration Outlook tables to replace illustrative cells with year-specific numbers before you lock a media plan.

Which nationalities should you target?

The nationality of movers is as important as the destination country. Who is relocating, and which nationalities tend to earn and spend at levels that justify specialised products?

Traditionally, many expat service providers focused almost exclusively on British and US citizens abroad. A closer look at highly qualified diaspora patterns tells a more varied story. Large skilled cohorts from India, Germany, and post-Soviet states, among others, sit in major financial and tech hubs. Marketers who only build creative and product UX for “Anglo expats” leave revenue on the table.

Some providers have already adapted. International insurers have expanded Russian- and German-language journeys; banks have launched accounts designed for nationals living abroad rather than forcing customers into resident-only onboarding. Those moves reflect a simple insight: diaspora wealth and mobility are not limited to the historic Anglo expat stereotype.

Example: nationality × product fit

The following example matrix is for internal workshopping, not a claim about market share.

Always validate with your own CRM: the highest-value nationality mix for a Dubai school will not match a Lisbon remote-work insurer.

Where the money actually moves

Market size debates become useful when tied to category economics:

  • Insurance and healthcare. International private medical insurance and related assistance products tend to track newly mobile professionals and families, not the entire migrant stock.
  • Banking and wealth. Multi-currency accounts, offshore structures and cross-border mortgages concentrate among higher earners and longer-horizon movers.
  • Telecoms and connectivity. Almost every arrival needs a local SIM or eSIM quickly; competition is fierce and price-led, so brand must show up at the decision moment.
  • Education. International schools sell to a thinner, higher-intent slice of the market: often parents already in-country or with an assignment letter in hand.
  • Relocation and housing. Peak demand sits in the pre-move and first-90-days window.

HSBC’s Expat Explorer (launched in 2008; recent waves commonly cite 4,000+ respondents across roughly 100 countries) and InterNations’ Expat Insider series are particularly helpful for qualitative ranking of destinations on cost of living, quality of life and family friendliness. They will not give you a single global TAM, but they help you prioritise messaging by city and life stage.

How to brief finance without overclaiming

When leadership asks for “the size of the expat market,” answer in layers:

  1. Global context: UN international migrant stock (~280M+ in recent DESA figures) establishes that cross-border living is mainstream, not niche.
  2. Addressable cohort: Define your ICP by income, visa type, tenure and product need. State explicitly what you are excluding.
  3. Geo priority list: Combine OECD / national inflow data with your historic conversion by country.
  4. Channel reality: Media inventory and language coverage vary wildly by city; stock alone does not equal reachable impressions.
  5. Scenario ranges: Present low / base / high planning cases labelled as estimates, then refine with pipeline data.

Illustrative budget allocation by objective

ObjectiveShare of test budget (example)Primary metric

Rebalance after one or two quarters; expat seasons and visa policy changes move demand faster than many domestic categories.

Practical takeaways for where to spend

So what should you tell your boss next time you are asked where to focus the expat budget? The picture remains imperfect, but several trends are clear:

  • There is a growing population of high-income professionals from markets such as India and wider Europe living abroad. While marketers have traditionally focused on western Anglo expats, adjacent audiences remain under-served in language, product design and media.
  • Traditional destinations like the US and UK still attract large numbers of highly skilled migrants, but Germany, Canada, the Gulf and selected Asian hubs repay close watching for inflow-led campaigns.
  • Foreign-born stock is a weak solo indicator. Pair it with annual inflows, income proxies and your own conversion data.
  • Use citeable sources carefully: UN DESA for global stock, OECD for destination flows, and survey programmes such as HSBC Expat Explorer or InterNations Expat Insider for lifestyle and destination insight, not as substitutes for each other.
  • Label any internal planning tables as illustrative until finance has signed off on the methodology.
