2010 Census Block Data - pluralities

Racial pluralities in NJ, from the 2010 Census.  Census block data from shape files provided by NJ GIS, including total population per block and population for white, hispanic, asian and black residents per block.  Blocks are colored according to the race that holds the plurality for that block.

And a closeup of Essex County, NJ.  Same data set, same color tables.

2010 Census Demographic Data - Block Level

These maps display population data from the 2010 Census, supplied as shape files from NJ GIS.  These shape files include census blocks from TIGER line data, joined with census demographic data from the SF1 dataset.  The data includes the total population for each census block and the population categorized as white, asian, black, hispanic, and native american.    Racial percentage is calculated as the racial population divided by the total population.  Major highways and county boundaries are also shown.    Data plotted with GRASS GIS.

Property taxes in SE Morris County

I've heard that the property taxes in Harding Township, Morris County, NJ are pretty reasonable compared to other towns in this area.  The map below shows the 2015 taxes paid for several municipalities in southeast Morris County, including

• Chatham Borough
• Chatham Township
• Harding Township
• Long Hill Township
• Madison Borough

Reds are the highest taxes and light aqua are the lowest.  For 0 tax parcels, I've coded them by use, and this time put in a legend.   The lot sizes in Harding are quite large, so while they do pay low taxes on a per acre basis,  taxes are still not so cheap.  The low tax parcels tend to be classified as farm land.  The other interesting thing to note is just how much open space there is in this part of Morris County. Pretty nice. 

Data from NJGIN and mapping done with GRASS GIS.

Property taxes in Essex County NJ

Here's a view of property tax payments in Essex County NJ, from 2015 data downloaded from NJGIN.  Sorry there's no scale (yet).   The light green colors are the lowest payments while the reds are the highest.  This map was drawn with GRASS GIS.   I'll update the post with scales and other useful info at some point.

Areas paying 0 tax are colored according to parcel use code.  A lot of that is public space, with parkland in very pale graygreen, schools in purple, and religious properties in light blue.

A lot of the red areas are commercial, and the residential customers paying the really high rates are heavily in Milburn, with Essex Fells, Montclair, and Maplewood also paying dearly.

NJ transport paths

I've started playing with geospatial data published by NJGIN.   My interests are mainly around demographics, wealth and tax distribution, and the relationships between demographics an geospatial features like terrain, proximity to transit networks, and so on. 

This map shows roads, train lines, and high tension power lines for New Jersey. The powerline data cam from HLFID.  Roads are shown down to the county level.  The map was produced with GRASS GIS.

 More maps to follow.  This first one's resolution is not so good, but I'll follow up with higher quality images in future maps.
