This document discusses using data analysis and visualization to understand social issues and help communities. It provides examples of analyzing government data on welfare recipients and homeless populations to identify service gaps. Maps are shown comparing rates of welfare across districts and over time. Correlation analysis reveals relationships between welfare and unemployment. The document advocates applying these techniques to better understand community needs and allocate resources more effectively.

“The chief business of eutopians was summed up
by Voltaire in the final injunction of Candide : Let
us cultivate our garden. The aim of the real
eutopian is the culture of his environment, most
distinctly not the culture, and above all not the
exploitation, of some other person's environment.
Hence the size of our Eutopia may be big or little; it
“
may begin in a single village; it may embrace a
whole region. A little leaven will leaven the whole
loaf.“
.“
“The notion that no effective change can be brought
about in society until millions of people have
deliberated upon it and willed it is one of the
rationalizations which are dear to the lazy and the
ineffectual.”
(p.307)
The Story of Utopias, by Lewis Mumford, (1922)
