District (PRC)
The term ''district'', in the context of China, is used to refer to several unrelated political divisions in both ancient and modern China. In the modern context, district (), formally city-governed district, city-controlled district, or municipal district (), are subdivisions of a municipality or a prefecture-level city. The rank of a district derives from the rank of its city. Districts of a municipality are prefecture-level; districts of a sub-provincial city are sub-prefecture-level; and districts of a prefecture-level city are county-level. The term was also formerly used to refer to obsolete county-controlled districts (also known as district public office). However, if the word ''district'' is encountered in the context of ancient Chinese history, then it is a translation for ''xian'', another type of administrative division in China. Before the 1980s, cities in China were administrative divisions containing mostly urban, built-up areas, with very little farmland ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Rate Of Natural Increase
In Demography, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. It is typically expressed either as a number per 1,000 individuals in the population or as a percentage. RNI can be either positive or negative. It contrasts to total population change by ignoring net migration. This RNI gives demographers an insight into how a region's population is evolving, and these analyses can inform government attempts to shape RNI. Examples Suppose a population of 5,000 individuals experiences 1,150 live births and 900 deaths over the course of one year. To show the RNI over that year as a percentage, the equation would be (1,150 – 900) ÷ 5,000 = 0.05 = +5% To show the RNI as a number per 1,000 individuals in the population, the equation would be (1,150 – 900) ÷ (5,000/1,000) = 250 ÷ 5 = +50 It can also be sho ...

Mortality Rate
Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "morbidity", which is either the prevalence or incidence of a disease, and also from the incidence rate (the number of newly appearing cases of the disease per unit of time). An important specific mortality rate measure is the crude death rate, which looks at mortality from all causes in a given time interval for a given population. , for instance, the CIA estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population per year. In a generic form, mortality rates can be seen as calculated using (d/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Per Mille
Per mille (from Latin , "in each thousand") is an expression that means parts per thousand. Other recognised spellings include per mil, per mill, permil, permill, or permille. The associated sign is written , which looks like a percent sign with an extra zero or o in the divisor. The term occurs so rarely in English that major dictionaries do not agree on the spelling and some major dictionaries such as '' Macmillan'' do not even contain an entry. The term is more common in other European languages where it is used to express fractions smaller than 1%. One common usage is blood alcohol content, which is usually expressed as a percentage in English-speaking countries. Per mille should not be confused with parts per million (ppm).

Birth Rate
The birth rate for a given period is the total number of live human births per 1,000 population divided by the length of the period in years. The number of live births is normally taken from a universal registration system for births; population counts from a census, and estimation through specialized demographic techniques. The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population. Natality is another term used interchangeably with 'birth rate'. When the crude death rate is subtracted from the crude birth rate (CBR), the result is the rate of natural increase (RNI). This is equal to the rate of population change (excluding migration). The total (crude) birth rate (which includes all births)—typically indicated as births per 1,000 population—is distinguished from a set of age-specific rates (the number of births per 1,000 persons, or more usually 1,000 femal ...

Female
Female (Venus symbol, symbol: ♀) is the sex of an organism that produces the large non-motile ovum, ova (egg cells), the type of gamete (sex cell) that fuses with the Sperm, male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, Sex-determination system, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced Secondary sex characteristic, secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sex Ratio
The sex ratio (or gender ratio) is usually defined as the ratio of males to females in a population. As explained by Fisher's principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. Many species deviate from an even sex ratio, either periodically or permanently. Examples include parthenogenic species, periodically mating organisms such as aphids, some eusocial wasps, bees, ants, and termites. The human sex ratio is of particular interest to anthropologists and demographers. In human societies, sex ratios at birth may be considerably skewed by factors such as the age of mother at birth and by sex-selective abortion and infanticide. Exposure to pesticides and other environmental contaminants may be a significant contributing factor as well. As of 2014, the global sex ratio at birth is estimated at 107 boys to 100 girls (1,000 boys per 934 girls).. Types In most species, the sex ratio varies according to the age profile of the populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Male
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...

2020 Chinese Census
The Seventh National Population Census of the People's Republic of China (), also referred to as the 2020 Chinese Census, was the seventh national census conducted by the National Bureau of Statistics of the People's Republic of China. Census work began on November 1, 2020 and continued through December 10, 2020, involving seven million census workers. The 2020 Chinese census covers all Chinese citizens living in mainland China, as well as those living abroad on temporary visas. Foreigners who live in the mainland for more than six months are also recorded in the data. The preliminary results were released on May 11, 2021, with a news conference being held on the same day. The release was originally planned to be in early April, but was delayed by a month. Census result The population of mainland China was 1,411,778,724 as of 1 November 2020. In addition, Hong Kong's population was 7,474,200 (provided by the Hong Kong SAR Government at the end of 2020) and Macau's populati ...

Residential Communities Of China
A residential community is a community, usually a small town or city, that is composed mostly of residents, as opposed to commercial businesses and/or industrial facilities, all three of which are considered to be the three main types of occupants of the typical community. Residential communities are typically communities that help support more commercial or industrial communities with consumers and workers.

Villages Of China
Villages (), formally village-level divisions () in China, serve as a fundamental organizational unit for its rural population (census, mail system). Basic local divisions like neighborhoods and communities are not informal, but have defined boundaries and designated heads (one per area). In 2000, China's densely populated villages (>100 persons/square km) had a population greater than 500 million and covered more than 2 million square kilometers, or more than 20% of China's total area. By 2020, all incorporated villages (with proper conditions making it possible) had road access, the last village to be connected being a remote village in Sichuan province's Butuo County.
