One of those different lenses comes from mapping the economy bottom-up, rather than top-down, aggregating microscopic experiences into a macroscopic view. In medicine, we use a variety of different tools, at different resolutions, to diagnose problems and when prescribing solutions: thermometers, blood pressure monitors, X-rays, CT scans, ultrasound and blood tests. Rarely does one of these measures provide all of the diagnostic answers. Using them in combination can, however, help reach robust clinical conclusions. And that “micro-to-macro” approach is commonplace when understanding other complex adaptive systems like the body, natural, physical and social. 3  Rajan (2019). Coyle (2014).

As in medicine, it can be measured using different tools at different resolutions. There are various metrics of societal health, in addition to GDP. For example, there has been increasing interest recently in measures of physical and mental health.6 A number of statistical agencies, including in the UK, now gather direct and indirect metrics of people’s well-being. Here we map a selection of those alternative metrics, based around health, wealth and happiness. A different sort of lens comes from viewing these metrics at different spatial resolutions – regional, local authority, postcode even. This allows a “micro-to-macro” jigsaw of the economy to be pieced together, as with other complex systems.
