What are construction starts?
Forecast contains both historical and forecasted construction starts data. ConstructConnect reports construction starts in terms of project value (nominal dollars) and square feet. For Forecast, this means that a start value is the estimate of the square foot value or total dollar value of construction work started in a given time period. Reported project values include the costs for labor and materials, overhead, interest and taxes paid during construction and contractor's profits.
There are minor differences in the definition of a start between the United States and Canada:
United States
For the U.S., a start is defined as the date that construction starts on a project. The start date is calculated as the bid date plus sixty days.
Canada
A Canadian start is defined as the date that a project reaches the start stage, as verified and reported by the Canadian ConstructConnect research team.

How frequently is the data updated?
Both historical and forecasted starts are updated on a quarterly basis, reflecting the most current macroeconomic and construction starts data. Currently the data is published in the last week of the month following the close of each quarter, in January, April, July, and October. Anchor differences differences
How are construction starts different from put-in-place construction spending?
Two of the most common ways to measure the construction market are construction starts and put-in-place:
- Put-in-place is an aggregate value of work done, regardless of when contractors are paid or when work is begun. Put-in-place excludes projects in the planning stage and is limited to reporting the final cost per month, which can in turn omit variables occurring over the lifetime of a project.
- By contrast, construction starts report the total project value or total square feet of projects at the time they are started. Starts are seen as a leading indicator of construction spending and investment.
Anchor sources sources
What are the data sources?
Overall, construction starts data is derived from the ConstructConnect database. Single family starts data is derived from the U. S. Census Bureau and Canada Mortgage and Housing Corporation, and macroeconomic data comes from Oxford Economics.
Anchor methods methods
What are the data collection methods?
ConstructConnect collects information on public and private construction projects across the United States and Canada.
The primary data collection methods are:
Reporting
- ConstructConnect reporters develop and maintain relationships with various sources throughout the construction industry including, but not limited to, owners, developers, architects, and contractors.
Partnerships and alliances
- ConstructConnect maintains strategic partnerships and alliances with key industry organizations to enhance data collection efforts.
Technology and automation
- ConstructConnect uses advanced technology and automation to aggregate information on public construction projects.
Anchor methodology methodology
What's the methodology used to forecast construction starts?
For ConstructConnect, a forecast is the calculated start on a project in the future. The forecast value is derived using historical starts from the ConstructConnect database and data modeling provided by Oxford Economics. As a forecast includes historical starts, the costs for labor and materials, overhead, interest and taxes paid during construction and contractor's profits are part of a forecast value. However, design costs, such as architectural and engineering, are not included.
The following table lists the drivers by sector that are used in determining starts.
| Sector | Short-term drivers | Long-term drivers |
|---|---|---|
| Residential | Unemployment rate, household liabilities, mortgage interest rates, house prices, population trends | House prices, personal incomes |
| Non-residential building | Output trends in relevant sector, population trends, capacity utilization, Borrowing costs, employment in relevant sector, disposable income | Output trends and employment in relevant sector |
| Civil engineering | Federal/State/Provincial spending, government borrowing costs, employment in government sector, output trends in relevant sector | Federal/State/Provincial spending, Output trends in relevant sector |

Why are historical starts data updated?
All projects reported by ConstructConnect are followed continuously by our network of reporters, ensuring that the starts data are consistently accurate even when projects are re-bid or abandoned.

What is the single-family methodology?
The data for single-family construction starts is a combination of unit, square foot and project values and extrapolated using a proprietary formula. While the methodology used is consistent for both the U.S. and Canada, there are some differences in the data sources:
United States
The U.S. single-family construction starts are derived using data from the U.S. Census Bureau.
Canada
The Canadian single-family construction starts are derived using data from CMHC (unit) and ConstructConnect (square foot and project).
