In 2022, the New Orleans-Metairie, LA metro area recorded the highest homicide rate of U.S. cities with a population over 250,000, at **** homicides per 100,000 residents, followed by the Memphis, TN-MS-AR metro area. However, homicide data was not recorded in all U.S. metro areas, meaning that there may be some cities with a higher homicide rate. St. Louis St. Louis, which had a murder and nonnegligent manslaughter rate of **** in 2022, is the second-largest city by population in Missouri. It is home to many famous treasures, such as the St. Louis Cardinals baseball team, Washington University in St. Louis, the Saint Louis Zoo, and the renowned Gateway Arch. It is also home to many corporations, such as Monsanto, Arch Coal, and Emerson Electric. The economy of St. Louis is centered around business and healthcare, and boasts ten Fortune 500 companies. Crime in St. Louis Despite all of this, St. Louis suffers from high levels of crime and violence. As of 2023, it was listed as the seventh most dangerous city in the world as a result of their extremely high murder rate. Not only does St. Louis have one of the highest homicide rates in the United States, it also reports one of the highest numbers of violent crimes. Despite high crime levels, the GDP of the St. Louis metropolitan area has been increasing since 2001.

This indicator provides information about publicly available recreational space per capita (acres per 1,000 population).Publicly available recreational spaces play an important role in communities, often conferring myriad health benefits. Access to places for physical activity, such as parks, trails, playgrounds, and community centers with recreational facilities, has been shown to prevent heart disease, stroke, diabetes, depression, and many types of cancer.Community recreational spaces also provide opportunities for park-related interventions that may reduce violent crime; serve as locations for outreach to increase access to and enrollment in health and social services; and provide space for community gardens and farmers’ markets, thereby increasing community access to fresh produce. Moreover, parks and other green spaces have environmental benefits that can protect community health through improved air quality and reduced impacts from the urban heat island effect .For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

This map features the top 100 SRTS school sites (Safe Route to School), school based attendance boundaries of the Los Angeles Unified School District. High school boundaries are shown in green, middle school boundaries are shown in blue, and elementary school boundaries are shown in red. This map may be used to locate an address, and in turn identify the Top 100 SRTS (Safe Route to School) elementary, middle, and high school assignment associated with that address, given that the subject address is located within LAUSD's boundary.

This physical structures points feature class represents current wastewater information in the City of Los Angeles. The maintenance hole structure is used to provide access to the sewer from the surface. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most rigorous geographic information of the sanitary sewer system using a geometric network model, to ensure that its sewers reflect current ground conditions. The sanitary sewer system, pump plants, wyes, maintenance holes, and other structures represent the sewer infrastructure in the City of Los Angeles. Wye and sewer information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.Associated information about the wastewater Physical_structure is entered into attributes. Principal attributes include:JUNCTION_SUBTYPE: junction subtype is the principal field that describes various types of points as either Diversion Structure, Drop or Drop Trap, Flush, Junction Chamber, Junction Structure, Maintenance, Offset, Other Structure, Siphon, Special Shallow, Special Structure, Terminal, Transition, Trap, Valve Vault, Weir. For a complete list of attribute values, please refer to (TBA Wastewater data dictionary). Wastewater Physical Structures points layer was created in geographical information systems (GIS) software to display the location of wastewater structures. The structures points layer is a feature class in the LACityWastewaterData.gdb Geodatabase dataset. The layer consists of spatial data as a points feature class and attribute data for the features. The points are entered manually based on wastewater sewer maps and BOE standard plans, and information about the points is entered into attributes. The physical structures points data layer differs from non-structures points data layer, such that physical structures points are maintenance holes. Reference the JUNCTION_SUBTYPE and MH_TYPE field for the type of structure. The STRUCTURE_ID field value is the unique ID. The wastewater structures points are inherited from a sewer spatial database originally created by the City's Wastewater program. The database was known as SIMMS, Sewer Inventory and Maintenance Management System. Structures information should only be added to the Wastewater Structures layer if documentation exists, such as a wastewater map approved by the City Engineer. Sewers plans and specifications proposed under private development are reviewed and approved by Bureau of Engineering. The Department of Public Works, Bureau of Engineering's, Brown Book (current as of 2010) outlines standard specifications for public works construction.
