Kazakhstan is officially a democratic, secular, unitary, constitutional republic with a diverse cultural heritage. Kazakhstan shares borders with Russia, China, Kyrgyzstan, Uzbekistan, and Turkmenistan, and also adjoins a large part of the Caspian Sea. The terrain of Kazakhstan includes flatlands, steppe, taiga, rock canyons, hills, deltas, snow-capped mountains, and deserts. Kazakhstan has an estimated 18.3 million people . Given its large land area, its population density is among the lowest, at less than 6 people per square kilometre (15 people per sq mi). The capital is Astana, where it was moved in 1997 from Almaty, the country's largest city.
Mongolia is divided into 21 Provinces (, often translated as aimags) and one provincial municipality. Each aimag is subdivided into several districts.
The modern provinces have been established since 1921. The capital, Ulaanbaatar, is governed as an independent provincial municipality separate from Töv Province, inside which it is situated.

Contemporary scholars consider modern Uyghurs to be the descendants of a number of people, including the ancient Uyghurs of Mongolia who arrived at the Tarim Basin after the fall of the Uyghur Khaganate, Iranic Saka tribes, and other Indo-European peoples who inhabited the Tarim Basin before the arrival of the Turkic Uyghurs. DNA analyses indicate that the peoples of central Asia such as the Uyghurs are all mixed Caucasian and East Asian. Uyghur activists identify with the Tarim mummies, remains of an ancient people who inhabited the region, but research into the genetics of ancient Tarim mummies and their links with modern Uyghurs remains problematic, both to Chinese government officials concerned with ethnic separatism, and to Uyghur activists concerned that the research could affect their people's claim of being indigenous to the region.
As of 2016, the total population of Afghanistan is around 33,332,025, which includes the 3 million Afghan nationals living in both Pakistan and Iran. Afghanistan's Central Statistics Organization (CSO) stated in 2011 that the total number of Afghans living inside Afghanistan was about 26 million and by 2017 it reached 29.2 million. Of this, 15 million are males and 14.2 million are females. About 22% of the population is urbanite and the remaining 78% live in rural areas.
The history of the Uyghur people, as with the ethnic origin of the people, is a matter of contention between Uyghur nationalists and the Chinese authority. Uyghur historians viewed the Uyghurs as the original inhabitants of Xinjiang with a long history. Uyghur politician and historian Muhemmed Imin Bughra wrote in his book "A History of East Turkestan", stressing the Turkic aspects of his people, that the Turks have a 9000-year history, while historian Turghun Almas incorporated discoveries of Tarim mummies to conclude that Uyghurs have over 6400 years of history, and the World Uyghur Congress claimed a 4,000-year history in East Turkestan. However, the official Chinese view asserts that the Uyghurs in Xinjiang originated from the Tiele tribes and only became the main social and political force in Xinjiang during the ninth century when they migrated to Xinjiang from Mongolia after the collapse of the Uyghur Khaganate, replacing the Han Chinese they claimed were there since the Han Dynasty. Many contemporary Western scholars, however, do not consider the modern Uyghurs to be of direct linear descent from the old Uyghur Khaganate of Mongolia. Rather, they consider them to be descendants of a number of peoples, one of them the ancient Uyghurs.
The Tibetan people () are an ethnic group native to Tibet. Their current population is estimated to be around 6 million. In addition to living in Tibet, significant numbers of Tibetans live in other parts of China, as well as India, Nepal, and Bhutan.
As of the 2014 Census, there are about 6 million Tibetans living in the Tibet Autonomous Region and the 10 Tibetan Autonomous Prefectures in Gansu, Qinghai and Sichuan, China. The SIL Ethnologue in 2009 documents an additional 189,000 Tibetic speakers living in India, 5,280 in Nepal, and 4,800 in Bhutan. The Central Tibetan Administration's (CTA) Green Book (of the Tibetan Government in Exile) counts 145,150 Tibetans outside Tibet: a little over 100,000 in India; over 16,000 in Nepal; over 1,800 in Bhutan, and over 25,000 in other parts of the world. There are Tibetan communities in the United States, Australia, Brazil, Canada, Costa Rica, France, Mexico, Norway, Mongolia, Switzerland, and the United Kingdom. In the Baltistan region of northern Pakistan, the Balti people are a Muslim ethnicity of Tibetan descent numbering around 300,000.
The Moscow trade expedition of the 1910s estimated the population of Urga at 60,000, based on Nikolay Przhevalsky's study in the 1870s.

On the other hand, ethnic Kazakhs and Uzbeks have been immigrating in large numbers to Kazakhstan ever since the collapse of the USSR. These immigrants come not only from the southern Central Asian states such as Uzbekistan and Tajikistan, but also from the Kazakh dominated areas in Xinjiang and Mongolia. The Kazakh government is actively encouraging the settlement of these compatriots (known as "Oralman") in Slavic dominated North and East Kazakhstan as well as the German dominated Karaganda Region, in order to dilute the minority populations there. There is also a low intensity immigration of ethnic Slavs from the less tolerant neighboring nations like Uzbekistan and Turkmenistan into Kazakhstan. An estimated 400,000 Uzbeks have migrated to Kazakhstan in recent years

The population of Tanzania as per the 2002 national census is 34,569,232. The majority of its citizens live in the rural villages, but with time the pace of migration to urban areas (especially youth) is increasing. In the rural areas unsustainable natural resource use push the population away, while social services and employment pull people towards the urban areas.
As of January 1, 2018 there are 15 statutory cities in Austria, 186 other cities, 770 market towns, and 1127 other communes, for a total of 2,098 municipalites. One of these municipalities stands out: the city of Vienna is a statutory city and a state at the same time. At 1,900,000 inhabitants, the national capital also seven times larger than the second most populous city, Graz.
The metropolis is an alpha global city as listed by the Globalization and World Cities Research Network. In 2011, the population of the city of Johannesburg was 4,434,827, making it the most populous city in South Africa. In the same year, the population of Johannesburg's urban agglomeration was put at 7,860,781. The land area of the municipal city () is large in comparison with those of other major cities, resulting in a moderate population density of .
The western two-thirds of the border are sparsely populated and traverse largely desert areas, in stark contrast to the western third which is densely populated, containing some of the largest towns in Uzbekistan and southern Kazakhstan. The eastern-most section is mountainous and contains a series of national parks (Sayram-Ugam National Park and Aksu-Zhabagly Nature Reserve in Kazakhstan and Ugam-Chatkal National Park in Uzbekistan. 
Uzbekistan’s Jizzakh to Sirdaryo railway crosses through Kazakhstan briefly, a legacy of the Soviet era where infrastructure was built without regard to what were then internal boundaries.
At , Mongolia is the 18th-largest and the most sparsely populated unitary sovereign state in the world, with a population of around 3 million people. It is also the world's second-largest landlocked country behind Kazakhstan and the largest landlocked country that does not border a closed sea. The country contains very little arable land, as much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to about 45% of the country's population. Ulaanbaatar also shares the rank of the world's coldest capital city with Moscow, Ottawa, and Astana.
Small settlements, like sum centers, may consist almost exclusively of ger districts. Even in Mongolia's capital Ulaanbaatar, around 62% of the population live in such districts. However, only about 43% of the ger district residents in Ulaanbaatar actually live in gers. Some of the districts in Ulaanbaatar have existed for more than 100 years, for example the one around Gandan, but many of those farther away from the city centre are the result of recent migration and the high price of other accommodation in Ulaanbaatar.
As of 2010, the population of Ulaanbaatar was 1,240,037 inhabitants and is increasing by nearly 100,000 people a year. The transport problem is exacerbated by the harsh climate and long winters. Traffic movement is difficult because of congestion, and the air is heavily polluted by exhaust fumes.
The company is charged with providing the following postal and communication services at the pot offices.
Of Mongolia's 3 million inhabitants, 30% are nomadic, and 61% of Ulaanbaatar's population live in informal settlements. This population had "no consistent addressing system" until May 2016 when Mongol Post started using a geocoding system provided by what3words.
