Countries frequently get compared to one another, and so do provinces and states and territories within countries. But we don’t usually compare provinces or states in different countries to one another.
Let’s do a bit of that now.
Above are the world’s 34 most populous ‘first-level administrative divisions‘ – provinces and states and territories and the like. (Statoids, they are sometimes called). 17 of the 34 are in China. 11 are in India, including the largest by far, Uttar Pradesh, which is home to more than 200 million people. All are in Asia except for Sao Paolo in Brazil and California in the US.
Some of the largest of these places used to be even bigger than they are now. Uttar Pradesh lost about 4.8 percent of its population and 18 percent of its territory when Uttarakhand broke off to become a state of its own in 2000. Sichuan, formerly China’s most populous province, lost about 26.4 percent of its population and 14.5 percent of its territory when Chongqing broke off in 1997. (Chongqing became one of China’s four Directly-administered Municipalities, the other three being Shanghai, Beijing, and Beijing’s port city Tianjin). And Guangdong, China’s most populous province today, lost about 7.5 percent of its population and 15.7 percent of its territory in 1988 when the island of Hainan became its own province.
Provincial Population as a Percentage of National Population
This chart above shows the size of countries’ largest provinces or states in relation to their overall populations. In the US, for example, it shows that the largest state (California) is home to approximately 12 percent of the country’s total population. In Canada, by contrast, the largest province (Ontario) is home to about 38 percent of the Canadian population. Argentina has a similarly high percentage of its population living in its largest province (Buenos Aires), but it also has a much bigger divide between its largest and second largest provinces than Canada or most other countries have.
The only country ahead of Argentina on the graph above is Pakistan, where the largest region (Punjab) has about 47 percent of the country’s population and the second largest (Sindh) has about 27 percent. But then, Pakistan only has 7 regions, whereas Argentina has 24 provinces.
I’ve tried to take this into consideration in the graph below. In this graph, the x-axis shows the number of first-level administrative divisions that each country has, while the y-axis shows the percentage of the country’s population that lives in its largest administrative division:
You can see that Argentina is still an outlier here. (As is Turkey, on the opposite end of the chart. Turkey has 81 provinces, yet still a sizeable chunk of its population living in its largest one, Istanbul). In fact, not only is Buenos Aires by far the most populous of Argentina’s 24 provinces, but it also surrounds the “Autonomous City of Buenos Aires”, which is itself the fourth most populous administrative division in the country.
Combined, the two Buenos Aires’ account for about 45 percent of Argentina’s population. (This partly reflects the fact that – according to the World Bank – Argentina is the most urbanized big country, tied with Japan and the Netherlands at 92 percent urban). In Argentina’s closely contested presidential elections in 2015, the two candidates in the race were the governor of the province of Buenos Aires and the Chief of Government of the Autonomous City of Buenos Aires, respectively. Buenos Aires also directly borders the country’s second and third most populous provinces, Cordoba and Santa Fe.
Argentina’s long neighbour Chile is similarly urbanized (88 percent of its population lives in an urban area), and similarly has more than 40 percent of its population living in the largest of its (16) regions, the Region Metropolitana de Santiago, where the country’s largest city is located.
Brazil too is highly urbanized (87 percent urban), but unlike Argentina and Chile, its second largest city, Rio de Janeiro, is not so much smaller than its largest city, Sao Paolo. Brazil has 27 first-level administrative divisions, the largest of which, Sao Paolo state, is home to about 22 percent of the country’s population. The country’s three most populous states (Sao Paulo, Minas Gerais, and Rio de Janeiro) directly border one another, and together account for 40 percent of the population.
In other big countries, like the United States, China, and India, the most populous provinces or states account for a smaller share of the total population. Guangdong is home to about 9 percent of China’s total population, California 12 percent of the US population, Uttar Pradesh 16.5 percent of India’s population. In the US, even clusters of states are fairly small: California and its immediate neighbours combined are home to only about 15 percent of the US population. (A similar 15 percent is in New York state and its immediate neighbours, or – overlapping somewhat with New York – in Pennsylvania and its immediate neighbours). Texas and its immediate neighbours account for only about 12 percent of the US population.
By comparison, Guangdong and its immediate neighbours are home to about 24 percent of China’s population. Henan and its immediate neighbours, in the more populous northern part of China, have about 33 percent of China’s population. And Uttar Pradesh and its immediate neighbours have about 42 percent of India’s population.
In Germany, the fifth most populous German state, Hesse, directly borders all five of the other most populous German states (North Rhine-Westphalia, Bavaria, Baden-Wurttemburg, Lower Saxony, and Rhineland-Palatinate). Together Hesse and its neighbours account for 78 percent of Germany’s total population. Hesse’s chief city is Frankfurt, a European finance and transport hub. The most populous of Germany’s 16 states, however, is North Rhine-Westphalia, home to 21.5 percent of the country’s population. Its largest city is Cologne. It is also the only state to border both the Netherlands and Belgium, which are themselves both densely populated too.
On the graph earlier, I included England, rather than Britain as a whole. Britain has four constituent countries, England being the largest of these of course, with 84 percent of Britain’s population. Within England, none of the nine regions shown in the map above has more than 15 percent of the English population. The three southeastern regions – London and its two surrounding regions – have about 45 percent of the English population.
A less demographically lopsided archipelago is Japan, where the largest regions are located in the centre of the country. This map shows 8 regions and47 prefectures; the largest region (Kanto, shown in green) accounts for about 34 percent of Japan’s population; the largest prefecture in that region (Tokyo) accounts for about ten percent of Japan’s population. The three central regions (Kanto, Chubu, and Kansai, shown in green, turquoise, and purple here) together are home to 97 million people, about 77 percent of the country’s population.
Above are 34 of the largest provincial economies, ranked by gross domestic product (in nominal terms). 13 of the 34 are in the USA, 9 are in China, and 13 are in other countries. The largest of these have economies bigger than those of major countries. California’s nominal GDP is greater than Britain’s, France’s, or India’s. Combined, the first-level administrative divisions shown on this chart account for between a quarter and a third of global economic output.
Finally, here are the 30 largest administrative divisions in terms of territorial size (in square kilometres). All 30 of these are larger than France. The largest of all, Russia’s Republic of Sakhka (also known as Yakutia), is nearly as large as India. 7 of the 30 places on this list are in Russia. 7 are in Canada. 5 are in Australia (that’s every Australian state, apart from the island-state of Tasmania). 4 are in China, 4 are in Brazil, 2 are in the US, and 1 is in Chad. Combined, these 30 administrative divisions occupy approximately 27 percent of the world’s land outside of Antarctica or Greenland. Yet they are home to only about 2.5 percent of the world’s population, 195 million people.
