The percentage levels and changes in Table 1 are based on the Census Bureau’s seasonally-adjusted (SA) August 2017 and earlier put-in-place construction statistics. ‘Put-in-place’ as a concept is meant to mirror work-in-process or progress payments as projects proceed.
For each type-of-structure, Table 1 takes the behind-the-scenes put-in-place data and compares the percentage changes of latest-12-months-over-previous-12-months versus latest-three-months-over-previous-three-months (annualized).
If the three-month percent change exceeds the 12-month percent change, then construction activity in that type-of-structure category is considered to be speeding up. A check mark is entered in the far right column. (If the opposite is occurring, a check mark is entered in the ‘slowing down’ column.)
If a type-of-structure category has a latest 3-month percent-change that is negative, but less negative, than its 12-month percent-change, such a circumstance is also considered to be an instance of ‘speeding up’ and warrants a check mark in the right-hand column. (Or, if it’s turning more negative, then it’s ‘slowing down’ further.)
