# Lake County, Indiana

Lake County is a county located in the U.S. state of Indiana. In 2020, its population was 498,700, making it Indiana's second-most populous county. The county seat is Crown Point. The county is part of Northwest Indiana and the Chicago metropolitan area, and contains a mix of urban, suburban and rural areas. It is bordered on the north by Lake Michigan and contains a portion of the Indiana Dunes. It includes Marktown, Clayton Mark's planned worker community in East Chicago.

## History
### Early settlement

Originally inhabited by the Potawatomi and generations of indigenous ancestors, Lake County was established by European Americans on February 16, 1837. From 1832 to 1836 the area that was to become Lake County was part of La Porte County. From 1836 to 1837 it was part of Porter County. It was named for its location on Lake Michigan. The original county seat was Liverpool, but in 1840 Lake Court House, later renamed as Crown Point, was chosen.
Lake County's population grew slowly before the 1850s. Construction of railroads to link Chicago to the rest of the country stimulated rapid development, and tens of thousands of settlers and immigrants bought land in the region. Small-scale industrialization began, but was primarily relegated to the northern coast of the county, where it could take advantage of the railroads along the coast and shipping on the Great Lakes. The 1900 Census gives a population of 37,892 residents.

### Industrialization and immigration

Inland Steel Company established a plant in East Chicago in 1903 and U.S. Steel founded one in Gary in 1906; with industrial jobs the demand for labor associated with industrial jobs, the county's population exploded. Immigrants poured into the area from all over Central and Eastern Europe (there was also a smaller Mexican immigrant community). In addition, both black and white migrants came from many regions of the United States, particularly Appalachia and the South. Mostly rural blacks went north in the Great Migration, seeking both industrial jobs and escape from Jim Crow violence and disenfranchisement in the South.
By 1930, Lake County's population surpassed 260,000, with first- and second-generation Americans constituting a majority of the population. The second wave of the Ku Klux Klan gained a large following here in the 1920s, as it did for a time in the rest of Indiana. The KKK organized against the numerous European immigrants, who were mostly Catholic. While the steel industry reigned supreme, other industries also found the county to be an ideal location for cheap land and well-developed transportation networks, such as automobiles, oil, chemicals, consumer goods, food processing, and construction supply companies.
The Great Depression was devastating to Lake County, as it was to other areas with economies based on heavy industry. The Depression, combined with industrial strife, changing demographics, and unionization, caused a realignment of politics in Lake County. It became a stronghold of the Democratic Party; Lake County has supported the Democratic nominee for president in every election since 1932 (exceptions occurred in 1956 and 1972). Indiana's 1st congressional district has elected Democratic candidates in every election since 1930.
World War II restored prosperity, as industry revived to support the war effort. Good economic times continued into the 1970s. During this period, unions helped industrial workers gain middle-class wages. In addition to attracting refugees and immigrants from Europe, black Americans and Mexicans migrated here in the postwar period in even higher numbers than in the 1910-1930 period. As minority populations exploded in such industrial cities as East Chicago and Gary, racial tensions surfaced again. Following construction of state and federal highways, development of cheaper land provided newer housing to middle-class people who could afford it. Both whites and established black families moved out of the aging industrial cities.

### Recent history

Lake County's population peaked at 546,000 in 1970. Severe industrial decline took place during the 1973-1991 period, brought on by foreign competition, new management philosophies that called for major workforce reductions, and productivity gains from technology. The decline was particularly intense in the steel industry: steel employment exceeded 60,000 in the 1960s, and declined progressively to just 18,000 by 2015. Lake County's population declined 13% to bottom out at 475,000 in 1990.
The industrial decline of the 1980s cast a long shadow over Lake County: the county did not regain the level of employment it had in 1980 until 1996, after which the employment level roughly flatlined. The county's economic output peaked in 1978, and has not since recovered, remaining 15-20% below the peak after adjusting for inflation. As prosperity declined, so did the immigration that powered the county's explosive population growth before 1950: per the 2000 census, only 5.3% of Lake County's residents were foreign-born, compared to over 11% for the United States as a whole.
The population recovered somewhat during the 1990s and 2000s, as the local economy adjusted. Suburban growth has also been driven by commuter populations of workers who are employed in Chicago and commute via expressways or the South Shore Line. In 2007, it was estimated that 44,000 workers commuted from Lake County, Indiana, to Chicago for work. The decline of industrial cities and growth of suburbs has been so sharp, that by 1990 a majority of the county's population lived outside of the four traditional industrial cities. Lake County still continues to struggle with urban decline and poverty, suburban sprawl and traffic jams, and a stagnating population.

## Geography

According to the 2010 census, the county has a total area of 626.56 square miles (1,622.8 km$^2$), of which 498.96 square miles (1,292.3 km$^2$) (or 79.63%) is land and 127.60 square miles (330.5 km$^2$) (or 20.37%) is water. It is the second-largest county in total area in Indiana, but has the largest water area of all 92 counties.
The northern and southern portions of the county (north of U.S. 30 and south of Lowell) are mainly low and flat, except for a few sand ridges and dunes and were both once very marshy and had to be drained. The lowest point, at 585 feet (178 m), is along the Lake Michigan shoreline.
The central part of the county is higher and hillier. As you travel south from the low and relatively flat lake plain in the northern part of the county, the land gradually rises in elevation until the peak of the Valparaiso Moraine. The highest point, at 801 feet (244 m), is in northeastern Winfield Township near 109th Street and North Lakeshore Drive in Lakes of the Four Seasons. From here the land descends south into the Kankakee Outwash Plain until the Kankakee River is reached.
The geographic center of Lake County is approximately 200 feet (60 m) northwest of Burr Street and West 113th Avenue in Center Township 41°24′53.8″N 87°24′14.3″W﻿ / ﻿41.414944°N 87.403972°W﻿ / 41.414944; -87.403972.

In spring and early summer, the immediate shoreline areas sometimes experience lake-breeze that can drop temperatures by several degrees compared to areas further inland. In summer, thunderstorms are common, occurring an average 40–50 days every year, and on about 13 days, these thunderstorms produce severe winds.

## Government

The county government is a constitutional body, and is granted specific powers by the Constitution of Indiana, and by the Indiana Code.
County Council: The county council is the legislative branch of the county government and controls all the spending and revenue collection in the county. Representatives are elected from county districts. The council members serve four-year terms. They are responsible for setting salaries, the annual budget, and special spending. The council also has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes, and service taxes.
Board of Commissioners: The executive body of the county is made of a board of commissioners. The commissioners are elected county-wide, in staggered terms, and each serves a four-year term. One of the commissioners, typically the most senior, serves as president. The commissioners are charged with executing the acts legislated by the council, collecting revenue, and managing the day-to-day functions of the county government.
Court: The county maintains a small claims court that can handle some civil cases. The judge on the court is elected to a term of four years and must be a member of the Indiana Bar Association. The judge is assisted by a constable who is also elected to a four-year term. In some cases, court decisions can be appealed to the state level circuit court.
County Officials: The county has several other elected offices, including sheriff, coroner, auditor, treasurer, recorder, surveyor, and circuit court clerk Each of these elected officers serves a term of four years and oversees a different part of county government. Members elected to county government positions are required to declare party affiliations and to be residents of the county.

Like the rest of the Rust Belt, however, Lake County has recently trended Republican, with Donald Trump scoring the highest percentage of the vote since 1972 in the 2024 presidential election.
Lake is part of Indiana's 1st congressional district, which is held by Democrat Frank J. Mrvan. In the State Senate, Lake is part of the 1st, 2nd, 3rd and 6th districts, which are held by three Democrats and one Republican. In the Indiana House of Representatives, Lake is part of the 1st, 2nd, 3rd, 11th, 12th, 14th, 15th and 19th districts, which are held by four Democrats and four Republicans.

### 2008 presidential primary

In the 2008 Democratic presidential primary on May 6, 2008, Lake County was one of the last counties to report results. Lake County had reported no results at 11 p.m. ET, and at midnight ET, only 28% of Lake County's vote had been reported. A large number of absentee ballots and a record turnout delayed the tallies, and polls closed an hour later than much of the state because Lake County is in the Central Time Zone. Early returns showed Senator Barack Obama leading by a potentially lead-changing margin, leaving the race between Senator Hillary Clinton and Obama "too close to call" until final tallies were reported.
