Public Cost per Home Constructed
From the graphs on public spending and constructed homes one can assess intention and effectiveness, respectively. From this graph we can discard a lack of spending (i.e., caring) as the single cause for such dismal results. By dividing the amount spent by the number of units constructed, we get the long-line plot as a measure of (in)efficiency. It is worth noting that the spending is based on constant Venezuelan Bolivar currency (year 2000).
The bars represent the average cost of constructing a home for the nine years previous to, then for the six years of, Chavez's administration. The costs per unit are actually higher because the numbers, here, of completed homes include both public and private sector constructions, which in 2003 had a ratio of about 4:1.
The short-line plot emphasizes and quantifies what is visually clear from the bars: It costs Chavez's administration more than twice as much to build one home than what it cost preceding administrations.
The difference between averages would be even greater if it weren't for the later completion of some homes that were begun before Chavez's administration. Only this administration's first year, the year in which homes from previous administrations were completed, has a value within the range of values of the preceding administrations. All other years, Chavez's administration's numbers have been higher than the highest in nine previous years!
Besides the high cost per unit of Chavez's administration, it is worth pondering as to whether the spikes in what should otherwise be values of attenuated changes are proof of corruption.
