No, it was a city survey. I think it would be wise, however, if we looked at the pre-war work of the City of Edinburgh in regard to housing. The corporation produced 14,694 houses during the 20 years between the wars. That was an average of 700 per annum. Now during the period since 1945 the corporation has built altogether in temporary and permanent houses 6,466, or an average of over 1,360 houses per year, which is nearly twice as many as the pre-war average built by the corporation.
