Overview

The Value of Construction Put in Place Survey (VIP) provides monthly estimates of the total dollar value of construction work done in the U.S. The United States Code, Title 13, authorizes this program. The survey covers construction work done each month on new structures or improvements to existing structures for private and public sectors. Data estimates include the cost of labor and materials, cost of architectural and engineering work, overhead costs, interest and taxes paid during construction, and contractor's profits. Data collection and estimation activities begin on the first day after the reference month and continue for about three weeks. Reported data and estimates are for activity taking place during the previous calendar month. The survey has been conducted monthly since 1964.

Why isn't the 'total construction' the sum of the other categories? It is! the trick is that the 'residential' and "nonresidential" categories are supposed to be below the 'total construction' level, and the other categories are below those two categories. This example of the data should make it more clear: http://www.census.gov/construction/c30/pdf/tot.pdf.

More information about the nature of the construction projects is also available.

Usage

This library has 1 function you can use.
(require "construction_spending.rkt")
(get-spending false)
Additionally, some of the functions can optionally return Big Data using an extra argument. If you use this Big Data, it may be much slower. Wait until you are sure your code is correct before using these examples.
(require "construction_spending.rkt")
; These may be slow!
(get-spending true)
