Modelling complex systems like cities requires a theory of how elements interact (e.g. transport influences trade, education and housing impact labour, etc.), tempered by the tractability measurements assumptions. Combining 2017 national UK Input-Output accounting table with local population sector employment tallies from Office National Statistics (ONS), we develop an Multi-Regional model novel spatial-interaction cost component to estimate trade between 48 their Gross Domestic Products (GDPs). We extend future scenarios via ONS projections over constant GDP growth 2% per year. Without external shocks, our results reflect so-called ‘North-South divide’: while northern may have higher GDPs than many southern (excluding London), economic output employee is lower. Our suggest prominence lower value-added sectors ‘Production’ in account for income worker, relative dominance ‘Financial insurance’ ‘Professional support activities’ cities.
