In the United States, a county or county equivalent is an administrative subdivision of a state or territory, typically with defined geographic boundaries and some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. Counties and other local governments exist as a matter of U.S. state law, so the specific governmental powers of counties may vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties. Some municipalities have been consolidated with their county government to form consolidated city-counties or have been legally separated from counties altogether to form independent cities. Conversely, counties in Connecticut and Rhode Island, eight of Massachusetts's 14 counties, and Alaska's Unorganized Borough have no government power, existing only as geographic distinctions.

The United States Census Bureau uses the term "county equivalent" to describe places that are comparable to counties, but called by different names. Louisiana parishes, the organized boroughs of Alaska, independent cities, and the District of Columbia are equivalent to counties for administrative purposes. Alaska's Unorganized Borough is further divided into 11 census areas that are statistically equivalent to counties. In 2024, the U.S. Census Bureau began to also recognize Connecticut's councils of governments, which took over some of the regional powers from the state's former county governments, as county equivalents.

The Mississippi River is the primary river of the largest drainage basin in the United States. It is the second-longest river in the United States, behind only the Missouri. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,340 mi (3,770 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km), of which only about one percent is in Canada. The Mississippi ranks as the world's tenth-largest river by discharge flow, and the largest in North America.

Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Many were hunter-gatherers, but some, such as the Mound Builders, formed prolific agricultural and urban civilizations, and some practiced aquaculture. The arrival of Europeans in the 16th century changed the native way of life as first explorers, then settlers, ventured into the basin in increasing numbers. The river served sometimes as a barrier, forming borders for New Spain, New France, and the early United States, and throughout as a vital transportation artery and communications link. In the 19th century, during the height of the ideology of manifest destiny, the Mississippi and several tributaries, most notably its largest, the Ohio and Missouri, formed pathways for the western expansion of the United States. The river also became the subject of American literature, particularly in the writings of Mark Twain.

The chemical industry comprises the companies and other organizations that develop and produce industrial, specialty and other chemicals. Central to the modern world economy, the chemical industry converts raw materials (oil, natural gas, air, water, metals, and minerals) into commodity chemicals for industrial and consumer products. It includes industries for petrochemicals such as polymers for plastics and synthetic fibers; inorganic chemicals such as acids and alkalis; agricultural chemicals such as fertilizers, pesticides and herbicides; and other categories such as industrial gases, speciality chemicals and pharmaceuticals.

Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians.

In 45 of the 50 states of the United States, the county is used for the level of local government immediately below the state itself. Louisiana uses parishes, and Alaska uses boroughs. In Connecticut, Massachusetts, and Rhode Island, some or all counties within states have no governments of their own; the counties continue to exist as legal entities, however, and are used by states for some administrative functions and by the United States Census bureau for statistical analysis. There are 3,242 counties and county equivalent administrative units in total, including the District of Columbia and 100 county-equivalents in the U.S. territories.

There are 41 independent cities in the United States. In Virginia, any municipality that is incorporated as a city legally becomes independent of any county. Where indicated, the statistics below do not include Virginia's 38 independent cities.

Most U.S. states and territories have at least two tiers of local government: counties and municipalities. Louisiana uses the term parish and Alaska uses the term borough for what the U.S. Census Bureau terms county equivalents in those states. Civil townships or towns are used as subdivisions of a county in 20 states, mostly in the Northeast and Midwest.

Population centers may be organized into incorporated municipalities of several types, including the city, town, borough, and village. The types and nature of these municipal entities are defined by state law, and vary from state to state. In addition to these general-purpose local governments, states may also create special-purpose local governments. Depending on the state, local governments may operate under their own charters or under general law, or a state may have a mix of chartered and general-law local governments. Generally, in a state having both chartered and general-law local governments, the chartered local governments have more local autonomy and home rule. Municipalities are typically subordinate to a county government, with some exceptions. Certain cities, for example, have consolidated with their county government as consolidated city-counties. In Virginia, cities are completely independent from the county in which they would otherwise be a part. In some states, particularly in New England, towns form the primary unit of local government below the state level, in some cases eliminating the need for county government entirely. Many rural areas and even some suburban areas of many states have no municipal government below the county level.

Texas (/ˈtɛksəs/ TEK-səss) is the most populous state in the South Central region of the United States. It borders Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and an international border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south and southwest. Texas has a coastline on the Gulf of Mexico to the southeast. Covering 268,596 square miles (695,660 km) and with over 31 million residents as of 2024, it is the second-largest U.S. state by both area and population. Texas is nicknamed the "Lone Star State" for the single star on its flag, symbolic of its former status as an independent country, the Republic of Texas.

Spain was the first European country to claim and control Texas. Following a short-lived colony controlled by France, Mexico controlled the land until 1836 when Texas won its independence, becoming the Republic of Texas. In 1845, Texas joined the United States of America as the 28th state. The state's annexation set off a chain of events that led to the Mexican–American War in 1846. Following victory by the United States, Texas remained a slave state until the American Civil War, when it declared its secession from the Union in early 1861 before officially joining the Confederate States on March 2. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation.

The Southeastern United States, also known as the American Southeast or simply the Southeast, is a geographical region of the United States located in the eastern portion of the Southern United States and the southern portion of the Eastern United States. The region includes a core of states that reaches north to Maryland and West Virginia, bordering the Ohio River and Mason–Dixon line, and stretches west to Arkansas and Louisiana.

Delict (from Latin dēlictum, past participle of dēlinquere ‘to be at fault, offend’) is a term in civil and mixed law jurisdictions whose exact meaning varies from jurisdiction to jurisdiction but is always centered on the notion of wrongful conduct.

In Scots and Roman Dutch law, it always refers to a tort, which can be defined as a civil wrong consisting of an intentional or negligent breach of duty of care that inflicts loss or harm and which triggers legal liability for the wrongdoer. Other civil wrongs include breach of contract and breach of trust. Liability is imposed on the basis of moral responsibility, i.e. a duty of care or to act, and fault (culpa) is the main element of liability. The term is similarly used in a handful of other English-speaking jurisdictions which derive their private law from French or Spanish law, such as Louisiana and the Philippines, but tort is the equivalent legal term used in common law jurisdictions and in general discussions of non-contractual liability.

Louisiana was a dominant population center in the southwest of the Confederate States of America, controlling the wealthy trade center of New Orleans, and contributing the French Creole and Cajun populations to the demographic composition of a predominantly Anglo-American country. In the antebellum period, Louisiana was a slave state, where enslaved African Americans had comprised the majority of the population during the eighteenth-century French and Spanish dominations. By the time the United States acquired the territory (1803) and Louisiana became a state (1812), the institution of slavery was entrenched. By 1860, 47% of the state's population were enslaved, though the state also had one of the largest free black populations in the United States. Much of the white population, particularly in the cities, supported slavery, while pockets of support for the U.S. and its government existed in the more rural areas.

Louisiana declared that it had seceded from the Union on January 26, 1861. Civil-War era New Orleans, the largest city in the South, was strategically important as a port city due to its southernmost location on the Mississippi River and its access to the Gulf of Mexico. The U.S. War Department early on planned for its capture. The city was taken by U.S. Army forces on April 25, 1862. Because a large part of the population had Union sympathies (or compatible commercial interests), the U.S. government took the unusual step of designating the areas of Louisiana then under U.S. control as a state within the Union, with its own elected representatives to the U.S. Congress. For the latter part of the war, both the U.S. and the Confederacy recognized their own distinct Louisiana governors. Similarly, New Orleans and 13 named parishes of the state were exempted from the Emancipation Proclamation, which applied exclusively to states in rebellion against the Union.

The Consulate General of the Republic of Indonesia in Houston (Indonesian: Konsulat Jendral Republik Indonesia di Houston) is Indonesia's diplomatic facility in Houston, Texas, United States.

The building is located at 10900 Richmond Avenue in the Westchase district. The facility serves the U.S. states of Arkansas, Alabama, Florida, Georgia, Louisiana, Mississippi, New Mexico, Oklahoma, Tennessee, and Texas. In addition, the Houston consulate serves Puerto Rico and the U.S. Virgin Islands. The consulate includes an exhibit of Indonesian culture.

The Gulf Coast of the United States, also known as the Gulf South or the South Coast, is the coastline along the Southern United States where they meet the Gulf of Mexico. The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the Gulf States.

The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism. The large cities of the region are (from west to east) Brownsville, Corpus Christi, Houston, Galveston, Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, Gulfport, Biloxi, Mobile, Pensacola, Panama City, St. Petersburg, and Tampa. All are the centers or major cities of their respective metropolitan areas and many contain large ports.

Tornado Alley, also known as Tornado Valley, is a loosely defined location of the central United States where tornadoes are most frequent. The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas, Louisiana, Oklahoma, Kansas, South Dakota, Iowa and Nebraska. Tornado climatologists distinguish peaks in activity in certain areas and storm chasers have long recognized the Great Plains tornado belt.

As a colloquial term there are no definitively set boundaries of Tornado Alley, but the area common to most definitions extends from Texas, through Oklahoma, Kansas, Nebraska, South Dakota, Iowa, Minnesota, Wisconsin, Illinois, Indiana, Missouri, Arkansas, North Dakota, Montana, Ohio, and eastern portions of Colorado, New Mexico and Wyoming. Research suggests that the main alley may be shifting eastward away from the Great Plains, and that tornadoes are also becoming more frequent in the northern and eastern parts of Tornado Alley where it reaches the Canadian Prairies, Ohio, Michigan, and Southern Ontario.

The Republic of Texas (Spanish: República de Tejas), or simply Texas, was a sovereign country in North America from March 2, 1836, to February 19, 1846. Texas was bordered by Mexico to the west and southwest, the Gulf of Mexico to the southeast, the two U.S. states of Louisiana and Arkansas to the east and northeast, and U.S. unorganized territory encompassing parts of the current U.S. states of Oklahoma, Kansas, Colorado, and Wyoming to the north. The Texas Revolution began when hostilities broke out on October 2, 1835, shortly before the regime of Mexican President and General Antonio López de Santa Anna adopted a new Mexican constitution known as the Siete Leyes that abolished the authority of the states under the federal republic and established a centralized government. The revolution lasted for over six months. On March 2, 1836, delegates in convention proclaimed the Texas Declaration of Independence. Major fighting ended on April 21, 1836, with the Treaties of Velasco that ended the fighting and secured Texas' independence.

The Mexican Congress refused to recognize the independence of the Republic of Texas, as the Treaties of Velasco were signed by Santa Anna under duress as prisoner. The majority of the Mexican Congress did not approve the agreement. Much of its territory was controlled and disputed by Mexico or the Comancheria; Mexico considered it a rebellious province during its entire existence. The Anglo-American residents of the area and of the republic were referred to as Texians, while Texans of Mexican descent were referred to as Tejanos.

The Atchafalaya River (/əˌtʃæf.əˈlaɪ.ə/) is a 137-mile-long (220 km) distributary of the Mississippi River and Red River in south central Louisiana in the United States. It flows south, just west of the Mississippi River, and is the fifth largest river in North America, by discharge. The name Atchafalaya comes from Choctaw for 'long river', from hachcha, 'river', and falaya, 'long'.

Louisiana, also known as French Louisiana, was a district of New France. In 1682, the French explorer René-Robert Cavelier, Sieur de la Salle erected a cross near the mouth of the Mississippi River and claimed the whole of the drainage basin of the Mississippi River in the name of King Louis XIV, naming it "Louisiana". This land area stretched from near the Great Lakes to the Gulf of Mexico and from the Appalachian Mountains to the Rocky Mountains. The area was under French control from 1682 to 1762 and in part from 1801 (nominally) to 1803.

Louisiana included two regions, now known as Upper Louisiana (la Haute-Louisiane), which began north of the Arkansas River, and Lower Louisiana (la Basse-Louisiane). The U.S. state of Louisiana is named for the historical region, although it is only a small part of the vast lands claimed by France.

The U.S. state of Louisiana is divided into 64 parishes (French: paroisses), making it the only state besides Alaska to call its primary subdivisions something other than "counties". Louisiana's usage of the term "parish" for a geographic region or local government dates back to the French colonial era and is connected to ecclesiastical parishes.

Thirty-eight parishes are governed by a council called a police jury. The remaining 26 have various other forms of government, including: council-president, council-manager, parish commission, and consolidated parish/city.
