This quote about how 80% of all data has a spatial component has been bandied around everywhere. Introduction to GIS classes, product descriptions, talks, etc. Would anybody know who first said it? Or A link to original article would be nice.

I just searched for "80% of data has a spatial component, says who?" and it returned this un-authoritative quote:
But a more reliable reference points to here:

A recent article from GISLounge sheds some light on the topic. It would seem that a certain Robert E. Williams wrote a paper in 1987 entitled "Selling a geographical information system to government policy makers." He was the Director of the Alachua County Regional Information Center at that time. The article was published in "Papers from the 1987 Annual Conference of the Urban and Regional Information Systems Association" by URISA. Here's the offending paragraph:
He doesn't lists any sources or supporting references to his claim though. |

Working in a local government... the 80% rule is generally true. Of course, if your business is manufacturing or retail, this percentage is non-applicable. In a local government, we do use the term NeoGeoData for data gathered and recorded with an adress or location component, not being a GIS dataset on purpose. This data becomes GeoData when you put this information in relation to other (Neo-)GeoData sets. (for instance "adresses of kids < 3 Years" versus "location of playgrounds") ("income" versus "age" versus "location of social housing") So yes, I think the statement "It has been estimated that approximately 80% of the informational needs of a local government policymaker is related to a geographical location" is quiet correct. |
