The reason you'll never see these stats is that Boks is not too hot on analysis. He appears to like flying by the seat of his pants. He has refused volunteer help for technical analysis from multiple sources including a former shelter director, me, and many others.
Scott Sorentino had the opinion that as you expand the shelters and the holding capacity of the shelters, all income and outcome statistics would increase: impounds, adoptions, euth, RTO, etc. because more animals would be impounded.
Boks claims the approximate 25% increase in impounds was due to the economic downturn.
The statistics below show that in most cases the new shelters do not cause a lot more animals to be impounded. Another set of figures from Brad Jensen show clearly that adoptions take off after a new shelter opens.
What the charts in the pdf below do show is that the overall increase in impounds appear more related to the economic downturn and mortgage problems. The flood of increased impounds began during June last year, has continued and is still climbing.
The shelters opened at various dates and the only shelter that seemed to show a New Shelter effect is West LA.
Brad Jensen's numbers and charts:
Very strangely, the Annex showed no change do to the economy. This probably is because of policy.
