This map contains information on the adult life stage collection and testing results of blacklegged ticks (most commonly seen in fall and late winter/early spring) from various locations across New York State. These ticks were tested in “pools”, groups of up to ten ticks per sample, for the human pathogen Powassan virus, also known as Deer tick virus. This map helps generate awareness on the tick populations that had pools that tested positive for Powassan virus.

The data presented here also depicts the number of sites sampled per county, as well as the total number of ticks tested. Both tick density and pathogen infection percentage can vary greatly within a very small area, and definitely vary widely within a county. Therefore, these data should not be used to broadly predict disease risk for a larger or smaller area, such as for the county or the town. They should be used simply to educate that there is a risk to ticks and tick-borne diseases.

Further below on this page you can find links to the Department of Health tick prevention page, a video link on how to safely remove a tick should it attach, and a link to a list of county health departments.

The point map shows school water lead sampling and results information reported by each NYS public school and BOCES . The initial view of the map is broken up into large geographic areas and displays the number of schools in each area. To drill down to a smaller geographic area, click directly on the area of the map or click the plus sign to zoom in on the map to view details for each school. The map can be filtered by county by changing it under the Filter tab.
The data is self-reported by the schools in response to a Department of Health electronic survey, and transferred to Health Data NY as is without edits or redaction. Schools will update their information on an ongoing basis as their water sampling progresses and the laboratory analysis results are reported back to them. The points on the map will display detail information as and when it is available.

The Post-secondary Immunization Survey collects aggregate data from institutions in New York State regarding the immunization status of all the students attending post-secondary institutions.

The dataset includes reports from all institutions on the immunization status of students (required by Public Health Law Section 2165 to be immunized) from school year 2012-13 to present.

Street tree data from the TreesCount! 2015 Street Tree Census, conducted by volunteers and staff organized by NYC Parks & Recreation and partner organizations. Tree data collected includes tree species, diameter and perception of health. Accompanying blockface data is available indicating status of data collection and data release citywide.

The 2015 tree census was the third decadal street tree census and largest citizen science initiative in NYC Parks’ history. Data collection ran from May 2015 to October 2016 and the results of the census show that there are 666,134 trees planted along NYC's streets. The data collected as part of the census represents a snapshot in time of trees under NYC Parks' jurisdiction.

The census data formed the basis of our operational database, the Forestry Management System (ForMS) which is used daily by our foresters and other staff for inventory and asset management.

To learn more about the data collected and managed in ForMS, please refer to this user guide:

This dataset includes the name and location of active mobile home parks operating in New York State. Active mobile home parks include only parks that were categorized as active (i.e., operating with accommodations for the placement of five or more mobile or manufactured homes) on the date the data was downloaded from a Department of Health database. This data also includes the date of the last inspection and violations of Part 17 of the New York State Code of Rules and Regulations that were identified during that inspection. Additionally, the data includes the park owner-operator, the number of sites within the park, the type of on-site water source and sewage disposal system serving the mobile home park, and whether a pool or beach is operated as part of the mobile home park. The location of the mobile home park includes its street address, city, state, zip code, municipality, and county.

2010 Neighborhood Tabulation Areas (NTAs) are medium-sized statistical geographies for reporting Decennial Census and American Community Survey (ACS). 2010 NTAs are created by aggregating 2020 census tracts and nest within Community District Tabulation Areas (CDTA). NTAs were delineated with the need for both geographic specificity and statistical reliability in mind. Consequently, each NTA contains enough population to mitigate sampling error associated with the ACS yet offers a unit of analysis that is smaller than a Community District.

Though NTA boundaries and their associated names roughly correspond with many neighborhoods commonly recognized by New Yorkers, NTAs are not intended to definitively represent neighborhoods, nor are they intended to be exhaustive of all possible names and understandings of neighborhoods throughout New York City. Additionally, non-residential areas including large parks, airports, cemeteries, and other special areas are represented separately within this dataset and are assigned codes according to their type (See NTAType field).

This map includes the name and location of active Temporary Residences operating in New York State. Active Temporary Residences include only facilities that were categorized as active (i.e., hotel, motel, or cabin colony occupied by or maintained for the occupancy by 11 people or more) on the date the data was downloaded from a Department of Health database. This data also includes the date of the last inspection and violations of Subpart 7-1 of the New York State Code of Rules and Regulations that were identified during that inspection. Additionally, the data includes the Temporary Residence owner-operator, building type, number of sleeping rooms within the facility, and whether a pool, beach, or food service establishment is operated as part of the facility. The location of the Temporary Residence includes its street address, city, state, zip code, municipality, and county.
