The Census Bureau does not recognize or release data for Boston neighborhoods. However, Census block groups can be aggregated to approximate Boston neighborhood boundaries to allow for reporting and visualization of Census data at the neighborhood level. Census block groups are created by the U.S. Census Bureau as statistical geographic subdivisions of a census tract defined for the tabulation and presentation of data from the decennial census and the American Community Survey. The 2020 Census block group boundary files for Boston can be found here. These block group-approximated neighborhood boundaries are used for work with Census data. Work that does not rely on Census data generally uses the Boston neighborhood boundaries found here.

The population density picture of Boston is generally a story of two Bostons: the high density central and northern neighborhoods, and the low density southern neighborhoods.The highest density areas of Boston are particularly concentrated in Brighton, Allston, and the Fenway area, areas of the city with large numbers of college students and young adults. There is also high population density in areas such as the Back Bay, the South End, Charlestown, the North End, and South Boston. These are all relatively small areas geographically, but have housing stock conducive to population density (e.g. multi-family dwelling units, row housing, large apartment buildings). The southern neighborhoods, specifically Hyde Park and West Roxbury, have significant numbers of people living in them, but lots sizes tend to be much larger. These areas of the city also tend to have more single family dwelling units. In that, there are fewer people per square mile than places north in the city. Census data reveals that population density varies noticeably from area to area. Small area census data do a better job depicting where the crowded neighborhoods are. In this map, areas of highest density exceed 30,000 persons per square kilometer. Very high density areas exceed 7,000 persons per square kilometer. High density areas exceed 5,200 persons per square kilometer. The last categories break at 3,330 persons per square kilometer, and 1,500 persons per square kilometer.How to make this map for your city

2020 Census data for the city of Boston, Boston neighborhoods, census tracts, block groups, and voting districts. In the 2020 Census, the U.S. Census Bureau divided Boston into 207 census tracts (~4,000 residents) made up of 581 smaller block groups. The Boston Planning and Development Agency uses the 2020 tracts to approximate Boston neighborhoods. The 2020 Census Redistricting data also identify Boston’s voting districts.

Demographic Data for Boston’s Neighborhoods, 1950-2019

Boston is a city defined by the unique character of its many neighborhoods. The historical tables created by the BPDA Research Division from U.S. Census Decennial data describe demographic changes in Boston’s neighborhoods from 1950 through 2010 using consistent tract-based geographies. For more analysis of these data, please see Historical Trends in Boston's Neighborhoods. The most recent available neighborhood demographic data come from the 5-year American Community Survey (ACS). The ACS tables also present demographic data for Census-tract approximations of Boston’s neighborhoods. For pdf versions of the data presented here plus earlier versions of the analysis, please see Boston in Context.

Throughout history, government and industries have neglected investments in some neighborhoods, especially communities of color, who are more likely to have fewer resources.

This map shows a comparable measure of crime in the United States. The crime index compares the average local crime level to that of the United States as a whole. An index of 100 is average. A crime index of 120 indicates that crime in that area is 20 percent above the national average.The crime data is provided by Applied Geographic Solutions, Inc. (AGS). AGS created models using the FBI Uniform Crime Report databases as the primary data source and using an initial range of about 65 socio-economic characteristics taken from the 2000 Census and AGS’ current year estimates. The crimes included in the models include murder, rape, robbery, assault, burglary, theft, and motor vehicle theft. The total crime index incorporates all crimes and provides a useful measure of the relative “overall” crime rate in an area. However, these are unweighted indexes, meaning that a murder is weighted no more heavily than a purse snatching in the computations. The geography depicts states, counties, Census tracts and Census block groups. An urban/rural "mask" layer helps you identify crime patterns in rural and urban settings. The Census tracts and block groups help identify neighborhood-level variation in the crime data.------------------------The Civic Analytics Network collaborates on shared projects that advance the use of data visualization and predictive analytics in solving important urban problems related to economic opportunity, poverty reduction, and addressing the root causes of social problems of equity and opportunity.

WHAT IS THIS TRACKER FOR?

The City of Boston is committed to increasing transparency in the processes around the Zoning Board of Appeal (ZBA). The Inspectional Services Department (ISD) at the City is tasked with ensuring compliance with the zoning code. If an application for a permit is refused because of a zoning violation, applicants are able to appeal the decision to the ZBA and ask for an exception, sometimes known as a “variance.” If the ZBA grants relief, then the appellant is able to continue with the process of obtaining a permit.

In order to provide greater transparency in the ZBA process, the City of Boston Zoning Board of Appeal tracker is now available on Analyze Boston. Each record in this tracker represents an appeal of a denied permit application; the original permit application is known as the “parent application.” To find out more information about the original permit application, visit our Permit Finder tool. To view a map of this data, visit our ZBA Tracker Map Tool.

To learn more about the ZBA process and how to file an appeal, visit our website.

WHAT DOES EACH STATUS MEAN?

Appeal Submitted - indicates that an appeal of a zoning refusal was successfully submitted into ISD’s tracking system, either in-person at ISD (1010 Massachusetts Ave.) or through the online application portal.

More Information:

• For detailed information on how to file an appeal, see this page on the ISD website.

Next steps:

• The appeal will undergo an initial review by City staff to ensure that all necessary information and documentation has been included.
• The appellant must pay a fee.

Community Process - indicates that City staff have completed their review and signed off for the appeal process to move onto getting community feedback.

Contact Information:

• Use the link below to find the Neighborhood Liaison from the Office of Neighborhood Services for the application’s location.

Next steps:

• The appellant will work with the Mayor’s Office of Neighborhood Services to engage with people who own adjacent properties, members of the local community, and other relevant stakeholders.

• Depending on the type of project, the Boston Planning and Development Agency may also conduct a review.

Hearing Scheduled - indicates that the appeal has been scheduled for a committee or subcommittee meeting of the ZBA. For this to take place, the Mayor’s Office of Neighborhood Services has notified ISD that the appellant has adequately engaged with the community that would be affected, should the zoning relief be granted.

Attendance Information:

• View a schedule of hearings at the ZBA webpage. Select an Upcoming Hearing to find the list of topics and how to attend.

Next steps:

• The appellant will attend the hearing in person (or through the virtual meeting). The appellant will provide the ZBA with reasons why an exception or variance to the zoning code should be granted and answer any questions from the ZBA.

• At the hearing, members of the public will be able to testify in support or against the appeal.

• The ZBA will discuss the appeal and vote to approve or deny.

Alternatively:

• The appellant can request a deferral; if allowed by the ZBA, during the hearing the appeal will receive a new hearing date.

• The appellant can withdraw the application; if allowed by the ZBA, it can be withdrawn without prejudice.

Hearing Rescheduled - indicates that the appeal’s scheduled committee meeting has been changed. This can happen for several reasons. For example, the appellant can request a deferral if they need more time to complete or update plans, or the board can defer an appeal if a quorum isn’t present (perhaps due to a recusal). A request for deferral is approved by the board, which also selects a new hearing date.

Next steps:

• Same as Hearing Scheduled above.

Hearing Concluded - indicates that the hearing has taken place. The appeal could have been approved, denied, deferred, or withdrawn, with or without additional requirements.

Additional Information:

• Meeting minutes from each committee meeting are available to download from the ZBA webpage.

Next steps:

• The ZBA Executive Secretary finalizes the Board’s decision in writing or the appellant’s attorney submits a finalized decision for ISD Legal Team review.

ZBA Decision Finalized - indicates the date on the ZBA’s written decision letter. The decision is listed under the ‘result’ field.

Next steps:

• Neighboring property owners are notified of the decision shortly after this date

• Beginning on the Final Decision Date, neighboring property owners and other involved parties who disagree with the ZBA’s decision have twenty days to file an appeal in Suffolk County Superior Court or Boston Housing Court. (For detailed information on the Zoning Commission and appeal process, please refer to Chapter 665 of the Acts of 1956, available here)

Appeal Closed - indicates the appeal’s outcome has been finalized and the twenty day Appeal period has ended.

Next steps:

• Depending on the ZBA decision, the appellant may or may not be able to continue the process for seeking the permit for which zoning relief was requested.

• If the ZBA approved or sustained with proviso, the appellant must take additional steps before continuing the permitting process.

WHAT DOES EACH RESULT MEAN?

Approved - means the zoning relief requested has been granted.

Approved with Proviso - means the zoning relief requested has been granted, with some conditions that must be fulfilled before the permitting process can continue. These conditions will be detailed in the written decision of the ZBA. Examples of such conditions could include: having the Boston Planning and Development Agency review updated plans; submitting more detailed plans; or obtaining additional engineer reports.

Denied - means the zoning relief requested was not granted. The appellant must wait a year before submitting a new appeal on a project for the same site.

Denied without Prejudice - means the zoning relief requested was not granted. However, the appellant only has to wait thirty days before submitting an appeal on a new project at the same site.

Withdrawn - means the appellant has chosen to remove the appeal from the ZBA’s consideration. The appellant does not have to wait a year to appeal the same zoning violations.

Note: If there is no result listed, it means that the ZBA has not issued its final written decision on the appeal. This may be the case even for appeals that have been heard by the ZBA.
