Hajdúszoboszló is a town in Hajdú-Bihar county, Hungary, 19 kilometres southwest of county seat Debrecen. It is the third largest town in Hajdú-Bihar county; the name comes from a Slavic personal name Soběslav. The town is located in the northeastern part of the Great Hungarian Plain. Three regions meet near the town: the Hajdúhát ridge to the north-north-east, the Hortobágy National Park to the north-north-west, the Great Sárrét and Berettyó region to the south. Szoboszló lies at an altitude of scarcely 100 to 110 metres above sea level and slopes towards Hortobágy; this is a landscape "where earth and sky meet", but not a monotonous plain for travellers accustomed to romantic mountains, since here and there the landscape is enlivened by the backwaters of the Tisza River with patches of reed, thousands of wild fowl, inviting groves. The surroundings are the renowned puszta, the "glorious plain". From historical data and archaeological finds, this part of the Great Plain was inhabited as far back as the Great Migrations.
Because of the natural resources and the convergence of trade routes, Vandals, Gepids and Avars alternated with one another in this area. Early in the reign of the Árpád Dynasty, the area was inhabited by populous communities; the first written mention of Szoboszló dates back to 1075, when King Géza I donated half of Szoboszló's royal duty taxes to the new abbacy to be established at Garamszentbenedek. With an ornate deed of gift dated 2 September 1606, István Bocskai, Prince of Transylvania, provided smallholdings for 700 Hajdú cavalrymen at the site of Szoboszló, destroyed by the Crimean Tartars. Henceforth the prefix Hajdú was attached to the settlement's previous Slavonic name, though the compound form - Hajdúszoboszló - only became widespread in the 19th century; the town led the customary, toilsome life of the small agricultural, stock-breeding towns of Hajdú County until well into the 20th century. An upswing began on 26 October 1925 with the discovery of the thermal spring in the course of drilling for oil and gas.
The medicinal water, tinged with natural iodine, led to the town's development into a resort spa, while agriculture retained its significant role after the discovery of the gas field. 1870 - 12,269 1920 - 17,722 1970 - 22,000 2002 - 23,874 2005 - 23,827 2009 - 23,295 The water park includes water slides, an olympic-sized swimming pool, a wave pool, while the spa features graded thermal pools, including a tepidarium and jacuzzi-type hot baths.

Hajdú-Bihar is an administrative county in eastern Hungary, on the border with Romania. It shares borders with the Hungarian counties Szabolcs-Szatmár-Bereg, Borsod-Abaúj-Zemplén, Jász-Nagykun-Szolnok and Békés; the capital of Hajdú-Bihar county is Debrecen. Together with Bihor County in Romania it constitutes the Biharia Euroregion; the area of the county does not form a geographical unit. The western part is a large flat area of the country; the county of Hajdú-Bihar occupies the eastern part of Hungary. Most of its territory is flat and is part of the Pannonian Plain region; the highest point hardly rises over 170.5 metres in the north. It seems that the county slopes to the south because the lowest point is situated in this part of Hajdú-Bihar and hits the 85 metres height; the wind and rivers shaped the land for thousands of years. First the area of the present-day Hungary was occupied by an inland sea. After some underground movement, the huge peaks of the Carpathians rose from this sea; the wild and rapid rivers of the mountains made that inland sea disappear.
The great Hungarian plain was formed by the alluvial deposits of the rivers, the wind began to work and from the great rocks became smaller and smaller sand-grains, the so-called loess. This makes a fertile soil. There are two great rivers in the Tisza and the Körös; the Hortobágy area was formed by the first one. It used to be the flood area of the Tisza river and after the river was controlled, the Hortobágy became dry, resulting in special fauna. Hajdú-Bihar county was created after World War II from Bihar. See the articles of those counties for the history before World War II. In 2015, it had a population of 537,268 and the population density was 87/km². Besides the Hungarian majority, the main minorities are the Roma and German. Total population: 546,721 Ethnic groups: Identified themselves: 485,877 persons: Hungarians: 461,809 Gypsies: 18,132 Others and indefinable: 5,936 Approx. 77,000 persons in Hajdú-Bihar County did not declare their ethnic group at the 2011 census. Religious adherence in the county according to 2011 census: Reformed – 158,513.
Highways no. 4, 33, 35, 42 and 47 lead to the county and the county can be reached Hajdú-Bihar via the M3 motorway. The total length of the public roads in the county is 1,511 km. 122 road bridges span the rivers and canals. The roads cross the national borders to Romania at the cities of Nyírábrány; the Hajdú-Bihar County Council, elected at the 2014 local government elections, is made up of 24 counselors, with the following party composition: Hajdú-Bihar County has 1 urban county, 20 towns, 10 large villages and 51 villages. Compared to the average, Hajdú-Bihar has a small number of inhabited places: 21 towns and 61 villages; the four largest cities – both by area and by population – are Debrecen, Hajdúböszörmény, Hajdúnánás and Hajdúszoboszló. For a long time these were the only ones with city/town status, the rest were only villages, but after 1979 – when Berettyóújfalu became a town – several villages were promoted.

In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, have the capability of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area, where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. In sociology, population refers to a collection of humans. Demography is a social science. Population in simpler terms is the number of people in a city or town, country or world. In population genetics a sex population is a set of organisms in which any pair of members can breed together; this means that they can exchange gametes to produce normally-fertile offspring, such a breeding group is known therefore as a Gamo deme. This implies that all members belong to the same species. If the Gamo deme is large, all gene alleles are uniformly distributed by the gametes within it, the Gamo deme is said to be panmictic.
Under this state, allele frequencies can be converted to genotype frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics. This occurs in Nature: localization of gamete exchange – through dispersal limitations, preferential mating, cataclysm, or other cause – may lead to small actual Gamo demes which exchange gametes reasonably uniformly within themselves but are separated from their neighboring Gamo demes. However, there may be low frequencies of exchange with these neighbors; this may be viewed as the breaking up of a large sexual population into smaller overlapping sexual populations. This failure of panmixia leads to two important changes in overall population structure: the component Gamo demos vary in their allele frequencies when compared with each other and with the theoretical panmictic original; the overall rise in homozygosity is quantified by the inbreeding coefficient. Note that all homozygotes are increased in frequency – both the deleterious and the desirable.
The mean phenotype of the Gamo demes collection is lower than that of the panmictic original –, known as inbreeding depression. It is most important to note, that some dispersion lines will be superior to the panmictic original, while some will be about the same, some will be inferior; the probabilities of each can be estimated from those binomial equations. In plant and animal breeding, procedures have been developed which deliberately utilize the effects of dispersion, it can be shown that dispersion-assisted selection leads to the greatest genetic advance, is much more powerful than selection acting without attendant dispersion. This is so for both autogamous Gamo demes. In ecology, the population of a certain species in a certain area can be estimated using the Lincoln Index. According to the United States Census Bureau the world's population was about 7.55 billion in 2019 and that the 7 billion number was surpassed on 12 March 2012. According to a separate estimate by the United Nations, Earth’s population exceeded seven billion in October 2011, a milestone that offers unprecedented challenges and opportunities to all of humanity, according to UNFPA, the United Nations Population Fund.
According to papers published by the United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion; this was about 12 years after world population reached 5 billion in 1987, 6 years after world population reached 5.5 billion in 1993. The population of countries such as Nigeria, is not known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have been born in the last 2000 years. Population growth increased as the Industrial Revolution gathered pace from 1700 onwards; the last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity beginning in the 1960s, made by the Green Revolution. In 2017 the United Nations Population Division projected that the world's population will reach about 9.8 billion in 2050 and 11.2 billion in 2100.
In the future, the world's population is expected to peak, after which it will decline due to economic reasons, health concerns, land exhaustion and environmental hazards. According to one report, it is likely that the world's population will stop growing before the end of the 21st century. Further, there is some likelihood that population will decline before 2100. Population has declined in the last decade or two in Eastern Europe, the Baltics and in the Commonwealth of Independent States; the population pattern of less-developed regions of the world in recent years has been marked by increasing birth rates. These followed an earlier sharp reduction in death rates; this transition from high birth and death rates to low birth
