No accurate statistics exist regarding the number of mice on the planet. These small rodents lead a secretive lifestyle, reproduce quickly, and inhabit almost everywhere, making an accurate count impossible. All existing figures are scientific estimates and extrapolations. The order of rodents includes about one thousand five hundred species, which constitutes nearly forty percent of all known mammal species. Global Population Estimates of the total population of mice and rats worldwide vary greatly. According to some sources, the total number of rodents on the planet exceeds three hundred billion individuals, which is about five times the world's population. According to other estimates, the population may be around one hundred and fifty billion, assuming that only in India there are about fifty billion rodents. More modest calculations, based on the ratio of \"four rodents per person,\" give a figure of about thirty billion. Distribution by Continents Mice inhabit all continents except Antarctica. The highest concentration is observed in regions with high human population density and developed agriculture, as these rodents are closely associated with human activity. The origin of all species of the mouse genus Mus is in Eurasia and Africa, from where they spread around the world with humans. Asia Asia leads in terms of the absolute number of mice. This is due to the region's large population, favorable climate, and extensive agriculture. In India alone, according to various estimates, there are from fifty billion rodents. In China, there are also billions of mice and rats. The greatest diversity of rodent species is observed in southern West Siberia and the mountains of Central Asia. North America The rodent population in the United States is estimated at hundreds of millions of individuals. A high concentration is noted in large cities, where mice find abundant food and shelter. The house mouse was brought to the New World with European settlers and has sprea ... Read more
