Meet the Canadian who developed a ranking system for all 3,141 U.S. counties

John McLean said he developed an interest a few years back when he became aware of the information gaps that existed in the U.S. municipal bond market.

If little else the numbers are staggering – two million data points.

But that’s the outcome when you set out to the build the first of its kind within the U.S., a ranking system according to social and economic factors its the three,141 counties for the reason that country.

In all, the rankings, compiled in Canada, derive from 36 data inputs. There’s info on demographics; environment (including data on global warming and declarations of disaster); home ownership; real estate taxes; social indicators (including education and crime levels) and personal infrastructure (for example levels of police and teaching.) That information originated from more than a dozen different government or government-related sources.

Known officially as The American County Review (ACRe), the job represents a lot more than eight months of toil by John McLean, who within the last 23 years had focused his attention on bond analytics, bond pricing and developing bond indexes, initially at Scotia Capital and many recently using the Toronto Stock Exchange.
