Particulate Matter (PM) are small particles that contain microscopic solids and liquid droplets that are suspended in the air which can be inhaled and cause health effects. PM range in size, but particles less than 10 mm present the greatest threat. Some particles are emitted directly from a source such as, smokestacks, fires, construction sites, etc. and others are a result of complex atmospheric reactions .
Check out this map that shows the average daily PM 2.5 by county in 2011. From the graph we see a three distinct darkly shaded clusters indicating a high amount of daily exposure. The first cluster includes counties in Nevada and Utah. The second cluster includes counties within Colorado, Wyoming, Kansas and Nebraska. The third and most prominent includes counties within various southern states such as, Mississippi, Alabama, Georgia, Tennessee, Kentucky, Indiana, Illinois, Ohio, Pennsylvania, Virginia, West Virginia and North and South Carolina. In contrast, we can see states such as Oregon, Texas, California and Arizona are shaded yellow indicating a lower daily average.

Check out this map that shows the years of potential life lost rate from years 2011 to 2013. The years of potential life lost rate, also known as premature mortality rate, measures the frequency in which people are dying. From the map we can see a pronounced cluster of states darkly shaded (Oklahoma, Missouri, Arkansas, Mississippi, Louisiana, Alabama, Georgia, Kentucky, Tennessee, West Virginia) indicating a large proportion of counties within these states had a high rate of premature deaths. In other words people who lived within these counties were dying at an early age. In contrast we can see counties within states such as, Maine, Road Island, Vermont are lightly shaded yellow/orange, indicating people who lived within these counties were dying at an older age.

According to the Center for Disease Control and Prevention (CDC) chlamydia is the most common bacterial sexually transmitted disease (STD) in the U.S.  largely affecting men and women between the ages of 20 to 24. If untreated chlamydia can cause detrimental damage to a women’s reproductive system. 
Check out this map which shows the incidence of chlamydia by US counties in 2013 per 100,000 population. From the map, we can see most of states have a couple counties that are shaded dark indicating a high rate of newly diagnosed cases. Overall, we can see most counties have newly diagnosed causes of chlamydia.

This map was put together by Meharry Medical College with data from 2010- 2014 from the America Community Survey. The data represents the percentage empty housing units across the US with the lightest color representing 1-12.4% and the darkest red color showing 44.9-81.3%.

This interesting webpage displays toxic locations or superfund sites throughout the US based on the year it was discovered, the type of waste, the site’s hazardous ranking score, population size near the site, and race around the location. Brooke Singer and team wanted to show the areas of these superfund sites and provide a map that the community could interact with. Check the site out at www.toxicsites.us
Below is a full view of the US in 2015 and under is zoomed in on New Jersey in the New Brunswick area. Thanks www.toxicsites.us for the interesting map!
Take a look at this interesting map we made on Mappler in collaboration with Planning Communities! The map is full of GIS layers that you can toggle to show various information such as crime, food, recreation, transit, and URISA health data in DC. The picture below shows URISA data marking sidewalks, intersections, homeless locations, and garbage. Visit the map to view all the data ! nj.mapplerx.com/map/urisahealth
Climate change is always a hot topic, literally. With the melting of the ice caps, the unstable polar vortex which influences the jet stream, and with temperatures becoming more extreme, it is no mystery that sea level is continuing to rise. We wanted to visualize the threat of sea level rise by making a map that shows the potential projections of how our coasts in New Jersey and New York could eventual look.
We zoomed in to focus on New York City and the Northeastern part of the New Jersey coastline. We gathered the information for sea level rise from usgs.gov and then created the map using our Mappler technology. The first image is what the coast currently looks like, with the second and third images showing possible sea level rise projections. Image 2 shows sea level rise projections for 2100 if climate change continues without us taking action. This projection shows a 2m rise, with the dark blue border showing the potential new coastline. Image 3 is the worse case scenario for the year 2100, meaning that this is what scientists are projecting if again no action towards stopping or slowing climate change takes place and if the Greenland ice sheet melts. Image 3 shows a 7m sea level rise, and as you can see the land taken is massive. These maps show the scary reality that we could face if climate change is not taken seriously. You think that the population and its growth are bad now? How about when we then have to face displacement of part of the population because land where they use to live is covered in water? Take action, educate on climate change, and do your part!
