There are more than 260 TLDs in use around the world, most of which are country code top-level domains (ccTLDs). The Country Codes of the World map includes 245 country codes, which encompasses all United Nations countries as well as numerous islands and territories. Each ccTLD is sized relative to the population of the country or territory, with the exception of China and India, which were restrained by 30% to fit the layout. At the other end of the spectrum, the smallest type size used reflects those countries with fewer than 10 million residents.
