Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U. S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast. Houston is the most populous city in Texas and the fourth largest in the U. S. while San Antonio is the second-most populous in the state and seventh largest in the U. S. Dallas–Fort Worth and Greater Houston are the fourth and fifth largest metropolitan statistical areas in the country, respectively. Other major cities include Austin, the second-most populous state capital in the U. S. and El Paso. Texas is nicknamed "The Lone Star State" to signify its former status as an independent republic, as a reminder of the state's struggle for independence from Mexico; the "Lone Star" can be found on the Texan state seal.
The origin of Texas's name is from the word taysha. Due to its size and geologic features such as the Balcones Fault, Texas contains diverse landscapes common to both the U. S. Southern and Southwestern regions. Although Texas is popularly associated with the U. S. southwestern deserts, less than 10% of Texas's land area is desert. Most of the population centers are in areas of former prairies, grasslands and the coastline. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the desert and mountains of the Big Bend; the term "six flags over Texas" refers to several nations. Spain was the first European country to claim the area of Texas. France held a short-lived colony. Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the union as the 28th state; the state's annexation set off a chain of events that led to the Mexican–American War in 1846.
A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, joined the Confederate States of America on March 2nd of the same year. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. Four major industries shaped the Texas economy prior to World War II: cattle and bison, cotton and oil. Before and after the U. S. Civil War the cattle industry, which Texas came to dominate, was a major economic driver for the state, thus creating the traditional image of the Texas cowboy. In the 19th century cotton and lumber grew to be major industries as the cattle industry became less lucrative, it was though, the discovery of major petroleum deposits that initiated an economic boom which became the driving force behind the economy for much of the 20th century. With strong investments in universities, Texas developed a diversified economy and high tech industry in the mid-20th century.
As of 2015, it is second on the list of the most Fortune 500 companies with 54. With a growing base of industry, the state leads in many industries, including agriculture, energy and electronics, biomedical sciences. Texas has led the U. S. in state export revenue since 2002, has the second-highest gross state product. If Texas were a sovereign state, it would be the 10th largest economy in the world; the name Texas, based on the Caddo word táyshaʼ "friend", was applied, in the spelling Tejas or Texas, by the Spanish to the Caddo themselves the Hasinai Confederacy, the final -s representing the Spanish plural. The Mission San Francisco de los Tejas was completed near the Hasinai village of Nabedaches in May 1690, in what is now Houston County, East Texas. During Spanish colonial rule, in the 18th century, the area was known as Nuevo Reino de Filipinas "New Kingdom of the Philippines", or as provincia de los Tejas "province of the Tejas" also provincia de Texas, "province of Texas", it was incorporated as provincia de Texas into the Mexican Empire in 1821, declared a republic in 1836.
The Royal Spanish Academy recognizes both spellings and Texas, as Spanish-language forms of the name of the U. S. State of Texas; the English pronunciation with /ks/ is unetymological, based in the value of the letter x in historical Spanish orthography. Alternative etymologies of the name advanced in the late 19th century connected the Spanish teja "rooftile", the plural tejas being used to designate indigenous Pueblo settlements. A 1760s map by Jacques-Nicolas Bellin shows a village named Teijas on Trinity River, close to the site of modern Crockett. Texas is the second-largest U. S. state, with an area of 268,820 square miles. Though 10% larger than France and twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Zambia. Texas is in the south central part of the United States of America. Three of its borders are defined by rivers; the Rio Grande forms a natural border with the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the south.
The Red River forms a natural border with Arkansas to the north. The Sabine River forms a natural border with Louisiana to the east; the Texas Panhandle has an eastern border with Oklahoma at 100° W, a northern border with Oklahoma at 36°30' N and a western
Tucumcari, New Mexico
Tucumcari is a city in and the county seat of Quay County, New Mexico, United States. The population was 5,363 at the 2010 census. Tucumcari was founded in 1901. In 1901, the Chicago, Rock Island and Pacific Railroad built a construction camp in the western portion of modern-day Quay County. Called Ragtown, the camp became known as Six Shooter Siding, due to numerous gunfights, its first formal name, was used only for a short time. After it grew into a permanent settlement, it was renamed Tucumcari in 1908; the name was taken from Tucumcari Mountain, situated near the community. Where the mountain got its name is uncertain, it may have come from the Comanche word tʉkamʉkarʉ, which means'ambush'. A 1777 burial record mentions a Comanche woman and her child captured in a battle at Cuchuncari, believed to be an early version of the name Tucumcari. In December 1951, a water storage tank collapsed in the city. Four were killed and numerous buildings were destroyed. Tucumcari is located at 35°10′10″N 103°43′32″W.
According to the United States Census Bureau, the city has a total area of 7.6 sq mi, of which, 7.5 sq mi of it is land and 0.13% is water. Tucumcari has a cool semi-arid climate characterized by hot summers. Rainfall is low except during the summer months, when thunderstorms associated with the North American monsoon can bring locally heavy downpours. Snowfall is light, with a mean of 19.4 inches or 0.49 metres and a median of 9.7 inches or 0.25 metres. Due to the frequency of low humidity, wide daily temperature ranges are normal; the record high temperature at Tucumcari was 109 °F on June 25, 1990 and June 28, 2013, the record low temperature −22 °F on January 13, 1963. The hottest monthly mean maximum has been 100.5 °F or 38.1 °C in July 2011 and the coldest mean minimum 12.4 °F or −10.9 °C in January 1963, although the coldest month by mean maximum was January 1949 with a mean high of 38.6 °F or 3.7 °C. The wettest calendar year has been 1941 with the driest 1934 with 6.13 inches. The most rainfall in one month was 11.19 inches in July 1950.
The most rainfall in 24 hours was 4.41 inches on June 21, 1971. The most snowfall in one year was 46.7 inches in from July 1918 to June 1919. The most snowfall in one month was 30.0 inches in February 1912. As of the census of 2000, there were 5,989 people, 2,489 households, 1,607 families residing in the city; the population density was 793.8 people per square mile. There were 3,065 housing units at an average density of 406.2 per square mile. The racial makeup of the city was 75.87% White, 1.29% African American, 1.39% Native American, 1.20% Asian, 0.22% Pacific Islander, 17.10% from other races, 2.94% from two or more races. Hispanic or Latino of any race were 51.41% of the population. There were 2,489 households out of which 29.8% had children under the age of 18 living with them, 45.4% were married couples living together, 15.3% had a female householder with no husband present, 35.4% were non-families. 31.7% of all households were made up of individuals and 14.7% had someone living alone, 65 years of age or older.
The average household size was 2.35 and the average family size was 2.93. In the city, the population was spread out with 26.0% under the age of 18, 7.5% from 18 to 24, 24.2% from 25 to 44, 24.8% from 45 to 64, 17.5% who were 65 years of age or older. The median age was 39 years. For every 100 females, there were 90.9 males. For every 100 females age 18 and over, there were 86.8 males. Income inequality rose from 1990 to 2000; the median income for a household in the city was $22,560, the median income for a family was $27,468. Males had a median income of $25,342 versus $18,568 for females; the per capita income for the city was $14,786. About 19.1% of families and 24.8% of the population were below the poverty line, including 29.5% of those under age 18 and 16.7% of those age 65 or over. Schools in Tucumcari cover all groups from daycare to post-secondary education. Tucumcari Early Head Start and Head Start Tucumcari Elementary School Tucumcari Middle School Tucumcari High School Mesalands Community College Legend has it that Apache Chief Wautonomah was nearing the end of his time on earth and was troubled by the question of who would succeed him as ruler of the tribe.
In a classic portrait of love and competition, his two finest braves and Tocom, not only were rivals and sworn enemies of one another, but were both vying for the hand of Kari, Chief Wautonomah's daughter. Kari knew. Chief Wautonomah beckoned Tonopah and Tocom to his side and announced, "Soon I must die and one of you must succeed me as chief. Tonight you must meet in combat to settle the matter between you, he who survives shall be the Chief and have for his wife Kari, my daughter." As ordered, the two braves met, in mortal combat. Unknown to either brave was that Kari was hiding nearby; when Tonopah's knife found the heart of Tocom, the young woman rushed from her hiding place and used a knife to take Tonopah's life as well as her own. When Chief Wautonomah was shown this tragic scene, heartbreak enveloped him and he buried his daughter's knife deep into his own heart, crying out in agony, "Tocom-Kari"! A slight variation of the Chief's dying words lives on today as Tucumcari, the mountain that bears this na
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
Texas's 13th congressional district
Texas District 13 of the United States House of Representatives is a Congressional District of the U. S. state of Texas that includes most of the Texas Panhandle, parts of Texoma and northeastern parts of North Texas. It winds across the Panhandle into the South Plains runs east across the Red River Valley. Covering over 40,000 square miles, it is the second-largest district geographically in Texas and larger in area than thirteen entire states; the principal cities in the district are Wichita Falls. The current Representative is Republican Mac Thornberry. According to the Cook Partisan Voting Index, it is the most Republican district in the country; this district, has not always been Republican. As late as 1976, Jimmy Carter won 33 of the 44 counties in this district, getting 60-70% in many of them. In 2012, this was President Barack Obama's lowest percentage of the vote in a congressional district, he received 18.5% of the vote. In 2016, this was Hillary Clinton's lowest percentage of the vote in a congressional district.
She received an lower percentage than President Obama in 2012, receiving only 16.9% of the vote compared to Donald Trump's 79.9%. List of United States congressional districts Martis, Kenneth C..

The XIT Ranch was a cattle ranch in the Texas Panhandle which operated from 1885 to 1912. Comprising over 3,000,000 acres of land, it ran for 200 miles along the border with New Mexico, varying in width from 20 to 30 miles; the massive ranch stretched through ten counties in Texas, at its peak handled 150,000 head of cattle. In 1879, the 16th Texas Legislature appropriated 3,000,000 acres of land to finance a new state capitol. In 1882, in a special legislative session, the 17th Texas Legislature struck a bargain with Charles B. and John V. Farwell of Chicago, under which a syndicate led by the Farwells, with British investors, agreed to build a new Texas State Capitol in Austin and to accept the 3,000,000 acres of Panhandle land as payment; the ranch stretched across all or portions of Dallam, Oldham, Deaf Smith, Castro, Lamb and Hockley Counties. Total expense for the Capitol building materials and labor amounted to $3,744,630.60, of which the Syndicate Company paid $3,224,593.45. In return, they received 3,000,000 acres.
Though Mathias Schnell won the contract for constructing the new building in Jan. 1882, but by May he had assigned all interest to Taylor and Company. This company was composed of Col. Abner Taylor of Chicago, Col. A. C. Babcock of Canton, John V. and Charles B. Farwell of Chicago. Abner Taylor was assigned company representative in June. Babcock inspected the Capitol Tract that same year, setting out from Tascosa on 23 March and arriving at the Yellow Houses on 27 April, his inspection noted the 1880 J. T. Munson survey, used to define the capitol lands, used the northwest boundary of the state defined by John H. Clark's 1859 survey. Clark's line defining the 103rd meridian, approved by Congress in 1891, turned out to be about one half mile west of the true meridian; the issue was not settled until John V. Farwell and President Taft were instrumental in passing a 16 Feb. 1911 joint resolution by Congress honoring the Clark line. This action saved Texas a strip of land 310 miles long. In order to raise the capital needed to fence the ranch, build houses and barns, provide water, purchase the cattle, John V. Farwell formed the Capitol Freehold Land and Investment Company, Limited, in London.
The money was raised through the sale of debentures paying 5 percent interest. Directors of the company included John V. and Charles B. Farwell, Walter Potter, Henry Seton-Karr, Sir William Ewart, Edward M. Denny, Baron Thurlow, the Marquis of Tweeddale, while the Earl of Aberdeen and Quintin Hogg were Trustees; the company existed until 1909, when all bonds had been redeemed,Company headquarters were located in the northern boundary of the ranch, at Buffalo Springs, with George Findlay directing business. Col. B. H. Campbell became general manager, Berry Nations range foreman; the ranch started operations in 1885, moving them onto the ranch. By 1887, the herd was maintained at about 20 acres per head. W. S. Mabry surveyed in the four-wire barbed wire fence line, by 1886, 781 miles of fence were in place, including a 260 mile long west line and a 275 mile long east line. Cross fences were added by the late 1890s to make 94 pastures, bringing the total to 1500 miles of fence. A telephone line connected Tascosa to Alamocitos in 1888.
Though the northern portion of the ranch had plenty of water near Buffalo Springs, the portion south of the Canadian River needed wells, which were surveyed in by W. S. Mabry. By 1900, the ranch had 335 windmills averaging 34 feet high, with 12-18 foot wheels, producing water from an average depth of 125 feet. Additionally, 100 earthen dams were constructed. Trail driver Ab Blocker devised the XIT brand; the brand was made with a five inch long straight bar, applied five times. Yet, the XIT brand was not immune from "brand burning" by rustlers, which involved burning the original brand into another brand. Cowboy legends kept alive the myth that the brand means "Ten In Texas." Each calf was branded with XIT on its side, the last numeral of the year on its shoulder, the number of the division on its jaw. The ranch was divided into 7 division headquarters, located at Buffalo Springs, Middle Water, Ojo Bravo, Rito Blanco, Spring Lake, Yellow Houses, with Bovina added later; each was equipped with residences, bunkhouses, store rooms, barns and two-wagon freight outfit.
Large warehouses were maintained at Tascosa in 1887, after the introduction of the Fort Worth and Denver Railroad, in Bovina, after it was connected to the J. J. Hagerman's Pecos Valley and Northeastern Railroad in 1898. General headquarters were moved to Channing in 1890; each division wrote a monthly report and an annual report containing details about the cattle, range weather, the men employed. Buffalo Springs became the steer ranch, Middle Water the cull ranch, while Ojo Bravo, Spring Lake and Yellow Houses became breeding ranges; the 10-12 cowboys working a division in the winter increased to 25-30 in the summer. Campbell's management led to the ranch becoming a "stopping place and rendezvous for a large number of bad men and criminals," in the words of A. L. Matlock. Matlock was picked by John V. Farwell to run the ranch in 1887. Matlock chose A. G. Boyce as his general range manager; the Texas Trail was used for trail drives connecting Tascosa to Dodge City until 1885. Afterwards, the Northern Trail connected Buffalo Springs to the XIT range on Cedar Creek, 60 miles north of Miles City, Montana.
That trail was used from 1886 until 1897. Over a period of 3 months, some 10,000 to 12,500 steers were moved f
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.
