Report	What you’ll find
Countries ranked by corporate tax rate	The headline statutory corporate income tax rate. It does not include local surcharges, reduced rates, exemptions, tax bases or incentives, so it is not the effective rate a particular company pays.
Countries ranked by standard VAT rate	The standard national value-added tax or goods-and-services tax rate. Reduced and zero rates, exemptions and territory-specific rules are outside this comparison.
Countries ranked by statutory minimum wage	The national statutory gross minimum wage per hour, in euros at the ECB rate, before tax and contributions and not adjusted for prices. The United States and Canada show the federal rate, and states and provinces often set a higher one; Japan shows the national weighted average of its prefectural rates. Destinations that set pay by collective agreement (Austria, Denmark, Finland, Iceland, Italy, Norway, Sweden, Switzerland) or have no national minimum (UAE, Saudi Arabia) are absent rather than ranked at zero.
Countries ranked by top income tax rate	The top statutory personal income tax rate. It is the rate on the highest bracket, not an effective rate, and it excludes social contributions, regional surcharges and the allowances that decide what anyone actually pays.
Standardized employee gross-to-net scenarios by country	Official model outputs for a single employee without children at 100% of the national average wage, keeping each country’s native currency, tax year and source assumptions.
Benefits newcomers may qualify for by country	A source-backed directory of public benefit schemes whose official rules name eligible residence or migration statuses and an official information or application route.
Language and integration programmes by country	Current official language and integration programmes, retaining programme scope, target groups and the direct official route.
Countries ranked by migrant integration policy (MIPEX)	The Migrant Integration Policy Index scores a country's policies on labour market mobility, family reunification, education, health, political participation, permanent residence, nationality and anti-discrimination. Higher is more favourable. This ranks the 39 destinations ImmigrationDB publishes, not every country MIPEX scores.
Countries with a family reunification route	Current family migration routes by destination with direct authority sources.
Countries with a highly skilled work route	Current highly skilled migration routes by destination, preserving the official route name and source locator.
Countries with an official digital-nomad or remote-work route	Current destination routes explicitly classified as remote or digital-nomad pathways, with the official source and exact locator.
Countries with startup or entrepreneur visa routes	Current entrepreneur and startup pathways by destination with route-specific official evidence.
Digital-nomad and remote-work visa income requirements	A threshold table that preserves original currency, period and gross/net language instead of silently converting or presenting approximations as legal rules.
Permanent residence routes by country	Current permanent-residence pathways by destination, without inferring eligibility across countries.
Schengen short-stay visa requirements and timing	One canonical, EU-source-backed report for short-stay eligibility, timing, insurance and core documents. Filing fees are deliberately excluded from this report.
Study visa routes by country	Current study migration routes by destination, using the accepted official route registry.
UK Skilled Worker visa salary threshold	A source-backed explanation of the general threshold, occupation going-rate comparison and lower-salary cases; it is not a single universal salary number.
Countries with the lowest published groceries and utilities total	A like-for-like country comparison using the current monthly groceries and utilities fields in euros. Rent and application fees are not included.
Countries with the lowest published household electricity price	Country comparison of the current reusable household electricity price in euros per kWh, without mixing commercial tariffs or application costs.
Cities with the highest published monthly salaries	Published gross monthly salary observations in euros across available countries and city hubs, with source scope and date retained.
Cities with the lowest published unemployment	A source-backed comparison of published unemployment percentages, with the geographic scope and date available in each source.
Countries ranked by GDP per capita	Current GDP per capita in US dollars for the 39 published destinations. It measures the size of an economy per person, not what a person earns or keeps.
Countries ranked by grocery price level	Eurostat's price level index for food and non-alcoholic beverages, EU average = 100: below 100 the same basket costs less than the EU average. It compares price levels, not what incomes buy. It covers the EU, EFTA, the UK and candidate countries only.
Countries ranked by labour force participation	The share of the working-age population in the labour force, employed or looking for work. It says how many people are in the market, not how easy it is to enter it.
Countries ranked by statutory paid annual leave	The minimum paid annual leave the law gives a full-time employee on a five-day week, in working days and without public holidays (Eurofound, 2022). Collective agreements and contracts often give more. Destinations outside the Eurofound comparison are absent rather than ranked at zero.
Countries ranked by usual weekly working hours	Average usual weekly hours of full-time employees in their main job, from the Eurostat labour force survey and the OECD for destinations outside it. It is what full-time work usually takes, not the legal limit, and it says nothing about overtime pay.
Countries with the highest published family income after groceries and utilities	Published monthly net family income minus the same-source groceries and utilities fields. Housing, childcare and filing fees are deliberately outside this comparison.
Countries with the highest published single income after groceries and utilities	Published monthly net income for a standardized single profile minus the same-source groceries and utilities fields. It is not a full disposable-income budget because rent is excluded.
Public employment services by country	Official public employment services, registration and job-search routes for newcomers, without treating private recruiters or unverified local offices as national coverage.
Cities with the highest physician coverage	Physicians per 100,000 residents ranked from verified observations with geographic scope retained.
Countries ranked by hospital beds per 1,000 people	Total hospital beds per 1,000 people from OECD and Eurostat health statistics. It is a national capacity measure, not a promise of local availability or access for an individual patient.
Countries ranked by practising physicians per 1,000 people	Practising physicians per 1,000 people from OECD and Eurostat health statistics. It describes national workforce capacity, not whether a newcomer can register with a doctor in a particular city.
Cities meeting the WHO PM2.5 annual guideline	Published cities whose annual PM2.5 mean is at or below the WHO 2021 guideline of 5 µg/m³. Values come from official measurement networks with the observation date retained.
Cities with the highest published annual rainfall	Published monthly precipitation normals totalled into an annual figure, ranked highest first. Every value comes from one national meteorological service and keeps its own source and period.
Cities with the hottest summers	The warmest month of each city's published monthly normals, ranked hottest first. This is an average daytime high for that month, not an all-time record temperature.
Cities with the lowest annual NO2	Published annual nitrogen-dioxide observations ranked from lowest to highest using one unit and metric.
Cities with the lowest annual PM2.5	Published annual PM2.5 observations in µg/m³, ranked from lowest to highest without mixing current readings.
Cities with the lowest published annual rainfall	Published monthly precipitation normals totalled into an annual figure, ranked lowest first. Low rainfall is not the same as few rainy days; the total says nothing about how it is spread through the year.
Cities with the mildest winters	The coldest month of each city's published monthly normals, ranked warmest first. This is an average night-time low for that month, not the coldest night on record.
Cities with the most published annual sunshine	Published monthly sunshine normals totalled into annual hours, ranked highest first. Sunshine hours are not relabelled as sunny days.
Cities with the strongest published PM2.5 and NO2 combination	Cities with both annual PM2.5 and annual NO2 are compared using a transparent average of their lower-is-better percentile ranks. The two original values and sources remain visible.
Major cities where the modelled January mean stays above freezing	Large admitted cities whose NASA POWER 2001–2020 coordinate-grid January mean is above 0°C. This is a consistent modelled comparison, not a guarantee that every winter day stays above zero.
Major cities with the coldest modelled January mean	The same NASA POWER 2001–2020 coordinate-grid layer ranked from the lowest January mean. Exact station and neighbourhood conditions can differ.
Major cities with the highest modelled annual precipitation	Annual precipitation is derived from the NASA POWER climatological daily rate × 365.25. It is not a rainy-day count.
Major cities with the highest modelled solar exposure	NASA POWER annual mean daily surface shortwave energy in kWh/m²/day. This is a consistent solar-exposure metric and is not relabelled as sunny days.
Major cities with the hottest modelled July mean	The same NASA POWER 2001–2020 coordinate-grid layer ranked by July mean temperature, with period and grid scope shown for every city.
Major cities with the lowest modelled annual precipitation	The same derived NASA POWER annual precipitation layer ranked low to high. Low millimetres do not mean few rainy days.
Major cities with the lowest modelled solar exposure	NASA POWER annual mean daily surface shortwave energy ranked low to high. The report does not infer cloud-free or sunny-day counts.
Regions and station proxies with the mildest published January temperature	Comparable January temperature rows across the currently published Denmark and Latvia regional/station layer. The table names the geographic grain explicitly.
Warmest published cities and hubs	Published annual mean temperatures across countries, with the source date and geographic grain retained for every row.
City hubs with the lowest published recorded-crime rate	Recorded incidents per 100,000 residents across capital, migration and major city hubs. Definitions vary by authority, so each row keeps its source and date.
Countries ranked by homicide rate	Intentional homicides per 100,000 people, from national statistics. It is one recorded-crime measure and not a general safety index; recording practice differs between countries and the source is named on every row.
Cities with the highest foreign-population share	Published cities ranked by the share of foreign residents using one percentage metric.
Cities with the largest foreign populations	Published city records ranked by the official number of foreign residents; definitions remain source-specific.
Countries ranked by life expectancy	Life expectancy at birth, in years, for the 39 published destinations. It is a population-level average, not a prediction for any individual.
Largest cities in ImmigrationDB	The largest published city records by official population, with one source and observation date per row.
Least densely populated cities	Published cities with the lowest official population density, retaining the source date and geographic scope.
Least populous countries in the current ImmigrationDB coverage	A country-level population comparison limited to the 39 destinations currently published by ImmigrationDB, using the latest 2025 World Bank observations.
Most densely populated cities	Published cities ranked by official population density using one people-per-square-kilometre metric.
Most populous countries in the current ImmigrationDB coverage	A country-level population comparison limited to the 39 destinations currently published by ImmigrationDB, using the latest 2025 World Bank observations.
Countries ranked by English proficiency	The EF English Proficiency Index, a test-based score for adults in countries where English is not the first language. Higher is stronger. Destinations where English is an official language carry no score and are absent from this table rather than ranked at the top.
Countries ranked by fixed broadband penetration	Fixed broadband subscriptions per 100 inhabitants. It measures how widely fixed connections are taken up, not the speed of any one of them.
Countries ranked by road traffic deaths	Road traffic deaths per 100,000 people per year, on one shared WHO observation year for all 39 destinations.
