In 1832, cholera broke out in Paris. Back then, there was not a single choropleth map in plain sight.
Two years later, an official commission presented a report on the epidemic, including a shaded map. It used 5-6 shades to represent the number of losses out of every 1,000 people.
This was the first officially used choropleth. It was immediately popular, bringing its inventor prominence and a permanent place in history.
Choropleths remain useful in public health, economics, and politics. The onset of Covid-19 made them the foremost data visualization tool for informing the public. Choropleths can track everything from what sidewalk is safest to walk on to which stores have masks available.
A choropleth map is a data visualization tool that visually shows certain qualities within a defined geographic area.
It uses colors, patterns, shading, or symbols proportionate to statistical variables.
Choropleth maps are used to pair data with its geographic location. They only work when the data set includes location-specific data such as the zip code, county, state, or even country.
Choropleth maps are a popular way of interacting with location-specific data. Users can use them to evaluate trends within one area or for regional comparisons. Regional patterns and themes are easily seen since the data is categorized and displayed in the correct map location.
Crowd-sourced open data sets make building them more accessible.
Choropleth maps have many use cases, particularly for visualizing socioeconomic or climate data.
Population density is one of the most basic ways a choropleth map is used. This is a staple way to evaluate simple information quickly.
Choropleth maps are incredibly useful for more complex socioeconomic factors. They’re used to visualize issues like unemployment, crime, school performance, and religious affiliation.
Political information is often mapped out geographically. Political campaigns use it to strategize, and the media uses it for visual reporting.
Choropleth maps provide an overview of location-specific economic data, such as per-capita income, household food levels, and wealth distribution.
The World Food Programme uses a choropleth to track global undernourishment and chronic hunger levels.
Public Health relies on choropleth maps as a core tool. Regional life expectancy, health outcomes, risk factors, health disparities, birth weight, and general conditions need to be mapped out.
Currently, choropleth maps are heavily relied on for visualizing up-to-date Covid-19 information. Publicly available choropleths use machine learning to analyze real-time, globally sourced information. Research organizations, scientists, medical professionals, public health officials, journalists, and the public can access this for their purposes.
When combined with cloud-connected medical devices, people can monitor real-time public health. Health tech companies use choropleths to display their user results. Medtech devices that monitor fevers create real-time hot spot choropleths.
Alternatively, choropleths help manage medical overflow by showing areas of reduced activity.
Choropleth maps generate informative reports from statistics like rainfall distribution, soil condition, per capita crop production, forest cover, recreational land availability, plant biodiversity.
They can also show the effects of weather across populations.
We can geographically map out the sentiment thanks to artificial intelligence, machine learning, and public social media.
This can enhance political campaigns, support marketing, and monitor for bots.
Choropleth maps have several benefits that stakeholders may find in handy for certain situations. Here are some of those advantages:
Drawbacks of choropleth maps come from critical data evaluation to arbitrary boundaries, along with how variable the represented conclusions can be.
Here’s the good news, DashboardFox includes the ability to create Choropleth maps!
Out of the box, DashboardFox includes many types of maps from all over the world, and if your region is not available, a simple message to our support team can typically get it added quickly.
As with the rest of DashboardFox, the ability to create a Choropleth map is codeless. Via our config panel, you can define your colors, you can define value ranges to color codes if desired, and you can define hover reports to show users specific statistics when they hover over a portion of the map, as well as drill-down reports if a user clicks on a specific map. DashboardFox even supports country-level to state map drill-downs (for the US).
Compared to its counterparts in the market today, DashboardFox might have the shorter end of the stick when it comes to built-in visualizations. Still, we think this is a positive because we focus on a core set of graphs and charts that everyone in the industry can easily understand.
DashboardFox’s simple and no-frills approach is proven to be sustainable and efficient in the long run, as it helps save you time, money, and manpower.
