A Certificate of Occupancy (CO) states a building’s legal use and/or type of permitted occupancy. New buildings must have a CO, and existing buildings must have a current or amended CO when there is a change in use, egress or type of occupancy. No one may legally occupy a building until the Department has issued a Certificate of Occupancy or Temporary Certificate of Occupancy. The Department issues a final Certificate of Occupancy when the completed work matches the submitted plans for new buildings or major alterations. It issues a Letter of Completion for minor alterations to properties. These documents confirm the work complies with all applicable laws, all paperwork has been completed, all fees owed to the Department have been paid, all relevant violations have been resolved and all necessary approvals have been received from other City Agencies.

This dataset contains all Certificates of Occupancy issued since 7/12/12.

This map shows the NYC Taxi Zones, which correspond to the pickup and drop-off zones, or LocationIDs, included in the Yellow, Green, and FHV Trip Records published to Open Data. The taxi zones are roughly based on NYC Department of City Planning’s Neighborhood Tabulation Areas (NTAs) and are meant to approximate neighborhoods, so you can see which neighborhood a passenger was picked up in, and which neighborhood they were dropped off in.

Population Numbers By New York City Neighborhood Tabulation Areas

The data was collected from Census Bureaus' Decennial data dissemination (SF1).
Neighborhood Tabulation Areas (NTAs), are aggregations of census tracts that are subsets of New York City's 55 Public Use Microdata Areas (PUMAs). Primarily due to these constraints, NTA boundaries and their associated names may not definitively represent neighborhoods.
This report shows change in population from 2000 to 2010 for each NTA.
Compiled by the Population Division – New York City Department of City Planning.

New York City Population By Community Districts

The data was collected from Census Bureaus' Decennial data dissemination (SF1) for the years 1970, 1980, 1990, 2000 and 2010.

The Squirrel Census (https://www.thesquirrelcensus.com/) is a multimedia science, design, and storytelling project focusing on the Eastern gray (Sciurus carolinensis). They count squirrels and present their findings to the public. This table contains squirrel data for each of the 3,023 sightings, including location coordinates, age, primary and secondary fur color, elevation, activities, communications, and interactions between squirrels and with humans.

It covers information about the incident as it relates to the assignment of resources and the Fire Department’s response to the emergency.

Active Dog Licenses.

All dog owners residing in NYC are required by law to license their dogs. The data is sourced from the DOHMH Dog Licensing System (https://a816-healthpsi.nyc.gov/DogLicense), where owners can apply for and renew dog licenses. Each record represents a unique dog license that was active during the year, but not necessarily a unique record per dog, since a license that is renewed during the year results in a separate record of an active license period. Each record stands as a unique license period for the dog over the course of the yearlong time frame.

Every year, all parents, all teachers, and students in grades 6 - 12 take the NYC School Survey. The survey ranks among the largest surveys of any kind ever conducted nationally.

Survey results provide insight into a school's learning environment and contribute a measure of diversification that goes beyond test scores on the Progress Report. NYC School Survey results contribute 10% - 15% of a school's Progress Report grade (the exact contribution to the Progress Report is dependant on school type). Survey questions assess the community's opinions on academic expectations, communication, engagement, and safety and respect. School leaders can use survey results to better understand their own school's strengths and target areas for improvement.

The NYC School Survey helps school leaders understand what key members of the school community say about the learning environment at each school. The information captured by the survey is designed to support a dialogue among all members of the school community about how to make the school a better place to learn.

New York City parents, students, and teachers reached new all-time participation highs on the 2011 School Survey. 960,191 surveys were submitted.

Larger NYC parks (generally >20 acres) are subdivided into smaller sections that make inspecting these parks feasible and efficient.  These sections are called "zones."   The size and boundaries usually conform to one or more of the following criteria:  Zones should be inspectable in 1-2 hours; zone boundaries should follow the park’s features (paths, tree lines, etc) whenever possible; and/or conform to pre-existing boundaries used to divide the park for maintenance; and/or define a cohesive area within the park (ballfields, wooded areas, etc).  Besides zones, this layer contains a handful of Sitting Areas that are part of larger parks but could not be defined as zones due to their smaller size.
