CITY PLANNING
<span>In the 19th century, the population continued to grow unabated, doubling between 1801 and the 1820's and then doubling again between then and 1851, to 400,000 souls. This was phenomenal growth transforming Manchester into Britain’s second city. Manchester continued to grow steadily down to the end of the century. </span>
WORK- <span>Young men and women poured in from the countryside, eager to find work in the new factories and mills. The mills paid relatively high wages and they also employed large numbers of children. As a consequence, families migrating to the city often saw a considerable rise in their incomes. But not all aspects of life in the factories were pleasant. The rise in child labour was of course undesirable from the perspective of child welfare.
CITY PLANNING- </span>Better wages were undoubtedly the greatest attraction of city life, but the higher incomes came at a price. City planning was in its infancy and much of the new workers’ housing was erected with little regard to quality.
