Advertising suggested that people should get away from the city (in an era of common and sooty commercial, industrial, and domestic coal burning) and enjoy the fresh air of less densely populated areas like Maplewood.

Maplewood's historic residential areas were mostly built from 1900 to 1910 and a number of well-preserved homes remain.

Maplewood is currently being revitalized by an influx of restaurants, businesses, and shops around Manchester Ave., Sutton Ave., and the Greenwood Historic District.

Up until 2018, under a local nuisance ordinance, a person who called the police for domestic violence more than twice in 180 days could face eviction.

In 2012, a woman was evicted from her home after she had called the police four times to request protection from physical assaults by her ex-boyfriend.

In 2017, the ACLU filed a lawsuit on behalf of the victim, claiming that the Maplewood nuisance ordinance violated the First Amendment right to petition the government for assistance, as well as the rights to travel, equal protection and due process.

[5] In 2018, the ordinance was revised to eliminate language that allowed officials to fine or evict people who were victims of crime.

[6] In 2021, residents of Maplewood elected Nikylan Knapper as the city's first black mayor.

[7] According to the United States Census Bureau, the city has a total area of 1.56 square miles (4.04 km2), all land.

[8] The 2020 United States census[10] counted 8,269 people, 4,345 households, and 1,762 families in Maplewood.

The mayor of Maplewood is elected at large by the community and serves a three-year term.

[14] Maplewood is served by the Blue Line of the St. Louis region's MetroLink light rail system.

It connects the Maplewood-Manchester light rail station with MetroBus routes and paratransit services.

Hanley Road turns into Laclede Station Road just before entering Shrewsbury to the south while Interstate 44 passes Maplewood just south of the city limits near Deer Creek.
