City of Alexandria -- Time Series Data
Tufte (2001) and other ambassadors of the visual display of data have shown us how easily it is to understand complex data when it is graphically represented in ways that our minds are designed to understand. Tufte argues that "experience with the analysis of data…is essential for achieving precision and grace in the presence of statistics, .but even textbook of graphical design are silent about how to think about numbers" (Tufte, 2001, p. 104). Tufke remarks, that "Illustrators too often see their work as an exclusively artistic enterprise -- the words "creative," "concept," and "style" combine regularly in all possible permutations -- a Big Think jargon for the small task of constructing a time-series a few data points long" (Tufte, 2001, p. 204). Visual display of data has other uses than simply an elegant way to view, appreciate, and analyze data. The process of completing a graphic display of data forces the issue of data integrity and completion of data sets. When data is missing in a graphic display, it is glaringly apparent. And the process of figuring out how to arrange data for best display generates an awareness of the assumptions that undergird the data collection -- and ultimately, the data analysis. When creating a visual display of data, the analyst has cause to "muse on the ineffable origins of…insights" (Gladwell, 2007, p. 40) . The analyst admits, if only privately, that "There are ten different things it can mean… -- all of those are possibilities. You can't just look at one behavior [or data point] in isolation" (Gladwell, 2007, p. 43). When the data just doesn't come together, we might do well to recall Averch's caveat, that "If we believe that the information to be gained by evaluation should be proportional to the decision makers' needs, time, budget, and attention, then conventional quantitative evaluations may be infeasible or inappropriate" (n.d., p. 292).
Indicator # 20 Median gross rent
Indicator Response #4 - Representing Variance in Time (2000 -- 2010)
By 2010, 18.8 million renters had at moderate housing cost burdens. The numbers climbed in 2008-2009 by 1.2 million, which is nearly twice the rise in 2007 -- 8.
More than 69% of the increase was among households paying more than half their incomes for housing. The number of severely burdened renters in 2009 was the largest annual increase over decades.

Indicator Reponse #5 - Representing Variance in Time (Cross-Sectional Data)
For minimum-wage workers, using the 1/3 of earned income standard, an affordable monthly rent is just $377. Many households that rent units have incomes well below that level, including the working poor and those living on fixed incomes. The full-time minimum-wage equivalent is $14,500. About 1/4 of all renters and about 1/2 of all renters who receive assistance have household incomes below that figure. In 2009, most assisted units rented for less than $600. Thirty-five percent rented for less than $400 and about 20% had rents in the range somewhere between those two figures. In rental units where tenets did not get assistance, in comparison, only 31% rented for less than $600 and just 8% rented for less than $400.

Indicator #22 Number of foreclosures
Indicator Response #4 - Representing Variance in Time (2000 -- 2010)
The 2009 foreclosure data from RealtyTrac indicates an increase year over year of 47% of national foreclosure rates. Foreclosure rates are reported to have leveled off in Q2 and Q3 2009. But economists anticipate a surge in the coming months as the breakdowns in the foreclosure processes are addressed. Also, adjustable-rate mortgages are due to reset, a substantive proportion of which are loans that do not require borrowers' income verification.
