Where is the pig capital of the world?
One way to look at it is where the most pigs are grown in a given region.
Looking at the distribution of pigs globally, there are many places where pig density exceeds 250 pigs per square kilometer, especially in China. In fact, almost half of the world’s pigs are raised in China. The top pig-producing region in the world is Sichuan, China, which produced about 53 million pigs in the year 2010, according to the data. Of the top 20 pig-producing regions in the world, 18 of them are in China, while Iowa and North Carolina are ranked 8th and 20th, respectively.
The fact that China raises more pigs than other country may not be surprising; it is the most populated country in the world, and more than 85 million people live in Sichuan
But another way to think about the pig capital of the world is places where pigs outnumber people. When you overlay global human population data with pig density, it’s apparent there are many places around the world where pigs outnumber people (we found 55 regions). The three with the highest pig to person ratio are highlighted below.
Three Places Where Pigs Outnumber People
Iowa takes the crown for pigs outnumbering people. About 22.5 million pigs were raised in 2010 in the state of Iowa, about seven pigs for every person. Pigs raised for slaughter typically don’t live for an entire year, though: it only takes them six months to get up to what the pork industry considers to be slaughter weight.
Denmark produced about 13 million pigs in 2010, which is impressive considering the country is only a bit larger than the U.S. state of Maryland. There are three regions in Denmark where pigs outnumber people: In Nordjylland (North Jutland), pigs outnumber people five to one; in Midtjylland (Mid Jutland) and Syddanmark (Southern Denmark) pigs outnumber people about three to one.
Just south of Northern Ireland, in the county of Cavan, pigs outnumber people four to one.

You can also use Resource Watch to explore the densities of people compared to the densities of chickens, goats, cattle, horses, sheep, ducks and water buffalo. In case you wanted to know the water buffalo capital of the world, it appears to be India:
The analysis was done in ArcGIS using data downloaded from Resource Watch, using the Zonal statistics tool with subnational political boundaries from the Database of Global Administrative Areas (GADM), Gridded Population of the World (GPW) from NASA’s Socioeconomic Data and Applications Center (SEDAC), and Gridded Livestock of the World Version 3, produced by FAO and the University of Oxford.
