Construction knowledge gap age differences

This is a section of Designing Buildiings Wiki report 'Fit for purpose - Big data reveals the construction knowledge gap'. Click here to see more of the findings.


Our data confirms that under 45s are 4 times more likely to look for knowledge online than over 45s. This may indicate a specific need for knowledge, particularly around the late 20’s and early 30’s, or may indicate a greater willingness to seek out and rely on online sources of knowledge rather than more traditional sources.

Whilst there is a great deal of similarity between the subjects accessed by different age groups, there are also some stark differences, as revealed by the image below. Older people appear to be progressively less interested in BIM, to the point that there is almost no interest at all from the 65+ age group, and there is also a drop in interest in education, research and innovation.

There is more interest in subjects such as health and safety, regulations, and planning permission.
