But the two most populous countries, China and India, have a higher male population by a margin. Therefore, there are more males than females in the world. If the populations of China and India are excluded, there are more females than males in the rest of the world. The sex ratio at...
B Women usually give birth to more males(男生) than females(女性). Around the world, the ratio(比率) of boys to girls is between 1. 04 and 1.07. That means there are between 104 to 107 male babies for every 100 female babies. But in many countries, males are the preferred sex(性别...
Current World Population (2025, February 24) This page features the world population data by country with live calculation based on the birth/death ratio. Whilst every effort is made to ensure the population information is correct and up to date, there may be changes which we are not aware ...
while females range between 265 and 400 pounds (120 to 182 kilograms). They can reach lengths of up to 8.3 feet (2.5 meters), including the tail. Their diet mainly consists of large ungulates, such aszebras, antelopes andwildebeests. ...
pollution significantly increased average life expectancy, with a gain influenced by individuals’ educational status—higher for males than females. Yin et al.42focused on the public health consequences of air pollution in 33 Chinese provinces from 1990 to 2017. Using the Global Burden of Diseases,...

The ASMR increased in 10/19 countries for males and 9/19 for females as well across most WHO regions. The mortality-to-incidence ratio (MIR) decreased in all countries and WHO regions. Trends in DALYs were variable across countries and WHO regions. While the incidence and mortality from KC...
The mortality of LRTIs has declined significantly during the past 30 years due to advances in anti-infective drugs, but it remains an important health issue for individuals, especially for the children and the elderly [2]. In the context of increasing population aging and ongoing drug-...

Males of some antelope species establish and maintain small individual territories, or leks, which estrous females enter to mate; human herding and penning disrupts this, interfering with the species’ reproduction (Walther1972). Domestic ungulates are not descended from lek breeders,...
We show that, globally, around 50% of the world’s urban population lived in areas where migration accelerated urban population growth, while a third of the global population lived in provinces where rural areas experienced positive net migration. Finally, we show that, globally, socioeconomic ...
