NatureScore®
NatureScore® measures the amount of health supporting natural elements for any location or polygon, and provides a numerical scale that ranges from 0 (largely built, less healthy environment) to 100 (largely natural, healthy environment).
Download Data

The considered elements are weighted to create the highest correlation with the predictive health impacts of given natural elements via a machine learning process.

Note that certain "natural" elements that have not demonstrated positive health correlations, like sand or rock, are therefore less valuable than live vegetation.

Additionally, to account for regional differences the weighting of natural elements varies (park space may be more impactful in Phoenix, while trees may be more impactful in Boston).

Nature Deficient
0 – 19.9

Low density of natural elements. Effort required for immersive nature exposure opportunities.

Nature Light
20 – 39.9

Moderate to low density of natural elements. Effort may be required for immersive nature exposure opportunities.

Nature Adequate
40 – 59.9

Balanced mix of natural and built environmental elements. Modest effort required for immersive nature exposure opportunities.

Nature Rich
60 – 79.9

Significant natural elements. Modest effort may be required for immersive nature exposure opportunities.

Nature Utopia
80 – 100

Abundant natural elements and nature exposure opportunities.

Go Deeper

Beyond census tracts, the NatureScore system can also provide more granular, custom data (down to 10-meter resolution). Data can be delivered for specific addresses, custom polygons, or in gridded city “heat-maps.” The NatureScore system can also be used to create predictive algorithms of nature’s impact on elements other than public health, including urban heat islands, real estate values, air quality, social/economic benefits, etc. Finally, the NatureScore Priority Index is also available, which layers in socio-economic data to identify areas of nature deficiency and other disadvantages.

NatureScore is currently available in North America with planned expansion to Europe and Australia.

FAQ

What is NatureScore?

NatureScore measures the amount and quality of natural elements of any location using a patent-pending system. NatureScore delivers a score from 0 (largely built environment with little health benefit) to 100 (largely natural environment with material health benefits). For example, an urban neighborhood is typically below 30 while a forest will be over 70. For each census tract, NatureQuant analyzes and blends various data sets and processed information, including satellite infrared measurements, GIS and land classifications, park data and features, tree canopies, air, noise and light pollution, and computer vision elements (aerial and street images). The considered elements are weighted to create the highest correlation with the predictive health impacts of given natural elements via a machine learning process. Note that certain "natural" elements that have not demonstrated positive health correlations, like sand or rock, are therefore less valuable than live vegetation.

The NatureScore's on this website are provided in national rankings at the census tract level from 1 to 100. The 2020 census tract boundaries are used. NatureScores by state or city can be self created from the national dataset or delivered under separate request.

What methodology was used to create the NatureScore datasets?

The following article explains the methodology that was used to create the NatureScore Data:

https://journals.sagepub.com/doi/epub/10.1177/08901171231210806b
Can I request a different version of NatureScore?

NatureScore can be created for any custom polygon or single point with radius of examination around the selected point(s). If you have a research question in need of a different version of NatureScore please contact NatureQuant Open here.

How can I use NatureScore?

NatureScore can be used for several different purposes. NatureScore can be used for research purposes. For example, using NatureScore, Marekm et al (2023) found that the risk of mental health was higher in nature deficient communities.

NatureScore can be used for governmental or non-profit activity. For example, the Arbor Day Foundation uses NatureScore to deliver trees to the urban neighborhoods of highest need.

Given the known relationships between nature proximity and heath, health systems and health care providers can use NatureScore to target program delivery by geographic location based on the area of greatest disadvantage. For example, the Centers for Medicare and Medicaid (CMS) is currently prioritizing numerous forms of environmental determinants of health to target program delivery.

NatureScore can be used for Environmental Justice screening tools - many of which lack a measurement of the mix between built and natural environments.
