Economic Growth: - Gross Value Added per Head
Gross Value Added (GVA) indicates the level of economic activity within an area by measuring its production of goods and services. It is a measure that allows comparison of areas, and highlights variations in performance with a region, and trends over time. The GVA figure (workplace based) divided by the total residential population (resident based) gives an estimate for GVA per Head, whilst not a measure of productivity it is, nevertheless, a widely used measure to indicate the economic well-being of an area and again, provides comparison/benchmarking with other areas.
