Dear Parv,<br>
<br>
I am quite sure, that QGIS is the most suitable software for your
kind of work. Presumably there is no function in ArcGIS, that has no
equivalent in QGIS - if you check out the "Vector" menu you get the
"Geoprocessing Tools" with buffer and many other functions. (May be
it's hidden in an extension, I am not really a QGIS expert) or check
out the other tons of extensions.<br>
<br>
I'd sugeest, that the better place for your questions around QGIS is
the QGIS user list, check out the QGIS website for the registration
link.<br>
<br>
Regards, Till<br>

<p class="MsoNormal">Hi QGIS Community,<o:p></o:p></p>
<p class="MsoNormal">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:<o:p></o:p></p>

style="color:#1F497D">Visualize Hispanic or 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.<o:p></o:p></span></p>

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…<o:p></o:p></span></p>

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.<o:p></o:p></span></p>

<p class="MsoNormal">As we’re a non-profit, we prefer Open
Source Ware over high cost ware like ArcGIS. 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 tract or 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
wanted to ask if QGIS was indeed the best suited software for
this purpose or is there something simpler out there I should
check out instead.<o:p></o:p></p>
