You&#x27;d have to correct the 47m GBP for nominal GPD&#x2F;capita growth to get a clearer sense.<p>Using the data from <a href="http:&#x2F;&#x2F;www.theguardian.com&#x2F;news&#x2F;datablog&#x2F;2009&#x2F;nov&#x2F;25&#x2F;gdp-uk-1948-growth-economy" rel="nofollow">http:&#x2F;&#x2F;www.theguardian.com&#x2F;news&#x2F;datablog&#x2F;2009&#x2F;nov&#x2F;25&#x2F;gdp-uk-...</a> and picking 1975 nominal GPD (28,742 mGBP) vs 2013 nominal GDP (399,834 mGDP), the 47 mGBP in 1975 become 654 mGBP in 2013.
