The LoDI National index is 52 for May 2013, up slightly from last month's value of 51. Because logistics and distribution is one of many other sectors in the national economy, the LoDI national index values have a narrower range than the greater Louisville LoDI index values. The highest value was 53 in Jan 2009 and lowest value was 47 in July 2010.

A graph of past index values is available on the webpage of the Federal Reserve Bank at St. Louis. See
