A closer look at the community of Ferguson, Missouri, where 18-year-old Michael Brown was killed:

___

HISTORY: Incorporated in 1894 by founder William B. Ferguson as a railroad depot, the town quickly grew into a hub for freight and passenger traffic and a bedroom community for city workers. It also attracted many freed slaves looking for a home after the Civil War.

Before school desegregation, Ferguson and other parts of north St. Louis County were predominantly white. The racial makeup changed as many white suburban families moved to outlying areas such as St. Charles County, parts of which are more than 40 miles from St. Louis. Today, Ferguson is nearly 70 percent black.

___

POPULATION AND POVERTY: By 2010, the census counted about 21,000 people in Ferguson, which is about 10 miles north of downtown St. Louis in the broader area known to locals as North County. Fewer than half of the approximately 9,100 homes are owner-occupied, and about a quarter of residents live below the federal poverty level.

___

COMMERCE: Ferguson is home of the global headquarters of Emerson Electric Co., a Fortune 500 company that employs more than 130,000 workers worldwide. Just outside the city limits is Express Scripts, the nation's largest company that manages pharmacy benefits. Earlier this year, the corporation announced a $56 million expansion that will add 1,500 jobs. Ferguson's former rail depot is home to a redevelopment effort aimed at promoting small businesses in a pedestrian-friendly corridor, with a weekly farmers market and outdoor concerts in the summer.

___

SCHOOLS: Several North County school districts — including the Normandy system from which Brown graduated — lost state accreditation because of declining test scores and other academic shortcomings. Some students from the failing districts were bused to better-performing schools in other districts.

___

RACIAL CONCERNS: A law enforcement official tells The Associated Press that a Justice Department investigation will allege sweeping patterns of discrimination within the Ferguson police department, jail and court.

The report could be released as soon as Wednesday and appears to bolster allegations from some Ferguson protesters who have said members of the city's predominantly white police force disproportionately target black motorists during traffic stops. A 2013 report by the Missouri attorney general's office found that Ferguson police stopped and arrested black drivers nearly twice as frequently as white motorists but were also less likely to find contraband among the black drivers.
