The UN counts five countries in Central Asia, not six. Here's what the map actually shows, why Kazakhstan and Uzbekistan don't match on size and population, and what the border crossings mean for an overland trip.

The Central Asia map on most official sources shows five countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. If a map includes Afghanistan too, that's a tourism or Silk Road framing, not the standard geographic one.
How many countries are in Central Asia? Five, under the UN geoscheme: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.
Not in the UN's statistical classification. Afghanistan is filed under Southern Asia, even though it borders the five republics and shares Silk Road history with them.

Kazakhstan holds about 68% of the region's land area but only roughly a quarter of its population. Uzbekistan is smaller by area but has the largest population in the region and is the only doubly landlocked country among the five.
Yes. Entering Tajikistan's Gorno-Badakhshan (GBAO) region requires a separate permit in addition to a standard Tajikistan visa, arranged before the trip.

Brunei's population figures disagree depending on who's counting, 'Malay' is a legal category covering seven distinct groups, and the capital's real size depends on where you draw the line. Here's what the numbers actually mean.
Which country is largest, and which has the most people? Kazakhstan holds about 68% of the region's land area but only roughly a quarter of its population. Uzbekistan is smaller by area but has the largest population in the region and is the only doubly landlocked country among the five.
Do I need a permit to drive the Pamir Highway? Yes. Entering Tajikistan's Gorno-Badakhshan (GBAO) region requires a separate permit in addition to a standard Tajikistan visa, arranged before the trip.
The UN geoscheme, the classification used for statistics and most official references, places exactly five countries in Central Asia: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Afghanistan is filed under Southern Asia in that same scheme, even though it shares borders, Silk Road history, and a good deal of mountain geography with the five republics.
Drawn as a shape, the region reads as a rough block: Kazakhstan's vast steppe across the north, bordering both Russia and China; Uzbekistan sitting in the middle, wrapped almost entirely by its neighbors; Turkmenistan along the southwest against the Caspian and Iran; and Kyrgyzstan and Tajikistan forming the mountainous southeast edge, where the Tian Shan and Pamir ranges push the border up against China and Afghanistan's narrow Wakhan Corridor. That corridor is the one place the five-country bloc and Afghanistan actually touch.
General-audience maps and Silk Road itineraries routinely fold Afghanistan into Central Asia anyway, which is probably why searches for "country in central asia" turn up conflicting answers. For a classroom quiz, the UN version is the one to cite. For a trip, the distinction matters less than the visa rules, border procedures, and security situation of each country taken on its own terms.
The table below lays out the full map of Central Asia countries, each with its capital and the trait that matters most for a traveler.
| Country | Capital | What stands out |
|---|---|---|
| Kazakhstan | Astana | Largest by land area; only one of the five bordering both Russia and China |
| Kyrgyzstan | Bishkek | Compact and mountainous; gateway to the Tian Shan via Torugart and Irkeshtam |
| Tajikistan | Dushanbe | Home to the Pamirs and GBAO, which requires a separate travel clearance |
| Turkmenistan | Ashgabat | Most restrictive for independent travelers, mainly on visa policy and border procedure |
| Uzbekistan | Tashkent | Smallest by area among the major Stans, most populous, and the region's only doubly landlocked country |
For the Pamir leg of this map, a dedicated Pamir Highway route guide on the Fortrip blog walks through the Dushanbe–Osh corridor stage by stage, which is worth reading alongside this overview before locking in dates.
According to the CIA World Factbook, whose country profiles underlie most regional data tables, Kazakhstan's land area is 2,724,900 km², roughly 68% of Central Asia's combined territory. The five republics together total approximately 4,004,451 km², with a combined population near 80 million — a regional aggregate built from separate national counts taken in different years, so read it as a rounded total rather than a single census figure.
Kazakhstan, despite its size, holds only about a quarter of that population. Uzbekistan runs the opposite way: it has the largest population in the region, about 37 million, roughly 46% of the regional total, packed into a fraction of Kazakhstan's territory and concentrated around the Fergana Valley and Tashkent. Read population density next to the map and the contrast explains itself: Uzbekistan reads as urban and agricultural at ground level, while Kazakhstan's interior reads as vast and empty at the same map scale.
All five countries are landlocked. Uzbekistan is doubly landlocked, meaning any route to open ocean has to cross at least two other countries first.
The Uzbekistan–Turkmenistan crossing routinely takes several hours, with thorough document checks and a mandatory health screening on entry. Budget an afternoon for it, not twenty minutes.
The Kyrgyzstan–Tajikistan border over the Kyzyl-Art Pass is commonly cited at around 4,280 meters in traveler trip reports and overland guides. No government border agency publishes a surveyed elevation for the post, and no official registry ranks staffed crossings by height, so take the figure as a widely repeated approximation rather than a measured fact. What's not in dispute: there's no public bus service across it, and the road on both sides is gravel. Most travelers arrange a private vehicle in advance or negotiate a ride with a cargo truck on the Tajik side.
The Kulma Pass is a separate crossing, connecting Tajikistan to China rather than looping back through Kyrgyzstan. It matters mainly to travelers continuing east, not to anyone doing the standard Dushanbe–Osh loop.
None of these crossings run on a fixed public transport schedule. If a route plan assumes a bus timetable at any of them, that assumption needs checking before departure, something worth running through an AI trip planner built for multi-country overland routes rather than single-city itineraries.
Entering Gorno-Badakhshan requires a separate permit in addition to a standard Tajikistan visa. It's usually applied for before the trip or alongside the visa itself, not picked up on arrival at the regional border.
Two numbers that circulate for this stretch of the trip, a permit cost of roughly $30 to $50 and a Dushanbe-to-Osh drive time of 3 to 4 days, both come from the same single commercial source, one overland tour operator's published guide to the route. Neither figure has been cross-checked against an independent second source here, so hold both loosely: check the current permit cost and process through Tajikistan's e-visa portal or a consulate directly, and plan the drive time around the more commonly reported 7 to 10 days rather than the 3-to-4-day minimum, which assumes no stops.
Skipping the permit step risks a turnaround at checkpoints inside GBAO itself, not just at the regional entry point. Cross-referencing visa and permit requirements against an actual route, say with an itinerary validator, catches this kind of gap before it becomes a problem at 3,800 meters with no cell signal.
Budgeting 7 to 10 days for the Dushanbe-to-Osh corridor leaves room for stops in Khorog and Murghab, rather than treating the drive as a straight transit.
Cellular coverage along the route is patchy at best. Offline maps downloaded before departure aren't a backup plan here, they're the plan.
Much of the highway sits above 3,000 meters, which makes altitude a real line item in the planning, not a footnote, especially for anyone arriving straight from a lower-elevation city like Dushanbe or Tashkent.
Laid against the Kyzyl-Art Pass crossing and the GBAO permit requirement, the Pamir leg of a Central Asia map is really its own trip within the trip, with separate logistics from the rest of the region. Travelers comparing costs across a longer Central Asia loop, including a Kazakhstan itinerary added on either end, can check what that adds up to on the pricing page before committing to a route.
