[Qgis-user] Population statistics in QGIS

[Madry, Scott]

Hi there. I am Scott Madry of UNC in Chapel Hill, and an active QGIS user.

Send me an email at  madrys at email.unc.edu<mailto:madrys at email.unc.edu>

and we can discuss what you are doing in more detail!

Hi QGIS Community,
I’m Parv, an analytics intern at the Latino Community Credit Union here in North Carolina. I’m tasked with finding and using GIS software to visualize both US Census data and our membership data at micro levels to determine best locations for expansions. As per my instructions, this means being able to:
-          Visualize Latino population by smaller units than zip codes.  We have worked with Census tracts in the past and that is ideal, but there are even smaller areas with population data, like census blocks.  If we can see in a map where the higher number of Latinos live and also see the streets so that we can imagine potential locations and draw areas around them, we could identify optimal locations.
-          If we get a proposal for a location, for example a realtor contacts us and says “I have a great place for rent at 1309 Cúcuta Dr,” we should be able to enter the address in the software and define an area around it, draw that area and know how many Latinos live there.  The areas could be circles, free shape forms, circles cut by major highways or barriers we would think people wouldn’t cross…
-          Of course we should be able to add our own data to the software, like those addresses of our current members, and be able to look at, say, total balances of members who live in a defined area.

I have installed QGIS and am currently exploring its capabilities via the user guide/training manual. I know I first have to do a join on census csv population data and block shapefiles. Assuming I’m able to do that, I am trying to find relevant sections that would show me how to do this micro level aggregation of population data. I believe in ArcGIS this is called “create buffers around a point” but I am not sure if this is the relevant way to do it in QGIS or not. I searched for buffers in the training manual but I still can’t tell if it means the same thing or is relevant for my purposes. I’m also going through the vector analysis and processing sections but end up getting lost on what’s relevant and what’s not. I would greatly appreciate it if someone could guide me on being more effective at looking at the relevant features for the above needs, as I am unfortunately new to using in-depth GIS softwares like this.

Sincerely
Parv
