Statistical information answers quantitative questions such as "How many ...?", "How much ...?", "What percentage ...?" Although most of this data is provided in tables or databases, some also appears within text. The two main sources of statistical data are government agencies and professional associations.
If the resources listed on this page contain a section/location for statistical data links will be provided, however, some sites disperse the statistical data throughout their publications. In the latter case a link is provided to the overall agency/organization site so that the site's search engine can be used to locate information by topic.
Resources are divided by these categories:
Construction and Infrastructure
Many professional associations collect data on their membership and/or their area of expertise. Although some make this data freely available on their website, others restrict the data to members only or may provide data only to news sites or journalists for a fee. The ASU Library cannot obtain the data if the association restricts it.
To find websites for professional associations:
Once in the website, look for a category or section labeled statistics or data. If no such section exists, use the site's search box to look for "statistics". If the site has a publications section, see if that has a separate search engine in which you can search for "statistics".
