- to reinforce the community's trust in the integrity of its government by guaranteeing convenient timely access to information about attempts to influence the government's decisions.

This dataset contains the list of all persons registered as engaging in lobbying activities. It is updated daily. You can learn more about the Lobbyist Registration and Regulation Ordinance here: https://www.boston.gov/departments/city-clerk/lobbying-city-boston

## LOBBYIST REPORT STATEMENTS

The City Clerk maintains the public records regarding Lobbyist/Entity/Client registrations and all report statements as required by the city ordinance.

- In the pre-2022 data, each report can be viewed by clicking on the attachment that is in blue to the right of the registration number and name of individual.
- In the 2022-to-present data, the report information is all available in the CSV file; the information is no longer being uploaded into a separate report.
- You may also utilize the Search Box to the right of the database to further define your search either by registration number or by name to view the reports you are specifically looking for in the database.

Non Public Schools

This point datalayer shows the locations of schools in Massachusetts. Schools appearing in this layer are those attended by students in pre-kindergarten through high school. Categories of schools include public, private, charter, collaborative programs, and approved special education. This data was originally developed by the Massachusetts Department of Environmental Protection’s (DEP) GIS Program based on database information provided by the Massachusetts Department of Education (DOE).

Census Data for 2022 Redistricting

The BPDA Research Division prepared Census data on total population, population by race and ethnicity, voting-age population, group quarters populations, and housing occupancy for use in the 2022 City Council redistricting process. These data reflect 2020 census block-level data from the 2020 Decennial Census P.L. 94-171 Redistricting Data aggregated to the 275 precincts (as amended April 6, 2022) and the 9 current City Council Districts. Also included are 2010 estimates for these geographies based on 2010 census block-level.

__Notes on coding of Race and Ethnicity:__

The data presented here follow the conventions recommended by the Department of Justice in their September 1, 2021 guidance on the use of race and ethnicity data in redistricting. This differs from other commonly reported race and ethnicity groupings in that it groups those reporting 2 races, one White and one non-White, as being members of the non-White race reported. Thus a person reporting White and Black would be categorized here as Black. All residents of Hispanic or Latino origin, regardless of reported race, are grouped together. This coding appears on page 12 of the guidance that can be found here:
https://www.justice.gov/opa/press-release/file/1429486/download

__Notes on 2010 data:__

For 2010 data the BPDA Research Division crosswalked 2010 census block data to 2020 boundaries using a combination of block assignment and areal interpolation based on Census Tiger shapefiles and the publicly available boundary files for Boston electoral geographies. For blocks split across 2020 boundaries the entire 2010 population was assigned to one side of the boundary if no residential structures within that block existed on the other side of the boundary. In cases where residential structures were present on both sides of the boundary, areal interpolation was used to assign the block's population and housing units based on the share of the land area of the block falling on either side of the boundary. These numbers will differ from those produced using different crosswalking methods.

Numina Sensor Measurement of Multimodal Activity and Shared Streets

This dataset is the resulting traffic volume data from a recent pilot of computer-vision sensors.

The following metrics were measured:
-Volume counts of people, bikes, cars, trucks, and busses passing through pilot project areas
-Volumes accounted for by mode and timestamped at up to 15-minute intervals
-Desire lines and movement patterns accounted for by mode


The primary purpose of this pilot was to understand the impacts of temporary street-level changes that would be implemented to facilitate a safe re-opening in the context of Covid-19. A secondary objective of the project was to evaluate a privacy-oriented solution to data collection in the public realm. 

Sensors were installed at three distinct locations:
-In the Seaport district on a commercial street with bike lanes (Northern Avenue)
-Downtown at a busy intersection next to the Boston Common (Tremont Street)
-And in Jamaica Plain where the southwest corridor convenes with a blue bike station and T stop (Jackson Sq.)

Zoning Reform Impact Tracker

### ***TO VIEW A FULL LIST OF THE DATA AND DEFINITIONS CLICK [HERE](https://data.boston.gov/dataset/zoning-reform-impact-tracker/resource/580ec03a-0894-42dd-958e-5156229ddb34)***

### **WHAT IS THIS TRACKER FOR?**

The Zoning Reform Impact Tracker (ZRIT) is intended to help assess the impact of changes to the Zoning Code and to identify trends in permitting and requests for zoning relief.

This dataset provides the City’s first-ever measures of: 

* By-right development (projects that do not require zoning relief) as a proportion of total development   
* Incomplete or abandoned projects, in order to better understand challenges in the zoning and development process  
* Proposed and permitted [accessory dwelling units](https://www.boston.gov/departments/housing/accessory-dwelling-units-adus-boston) (ADUs)  
* The most common dimensional zoning violations by permit  
* The time that projects take to go through the [Zoning Board of Appeal](https://www.boston.gov/departments/inspectional-services/zoning-board-appeal), a regulatory body that grants or denies zoning relief   
* The time between applying for a building permit and when the building permit is issued  
  * Note: Building permits are issued by the Inspectional Services Department, but timelines to issuance are impacted by varied and complex development requirements, including additional reviews by the Parks Department, the Landmarks Commission, and the Planning Department, among other entities. 

Each Tracker record represents an application for a type of building permit submitted on or after January 1, 2018, including: substantial changes and repairs to the structure (“Alteration”), a change to a previously submitted application (“Amendment”), certain changes to an outdoor portion of land (“UOP”), or new construction (“Erect”).
