The city had the harshest working conditions for men women and children, but the children had it the worst. Kids worked in deadly conditions in occupations such as coal mining, chimney sweeping, and in factories. The 19th century was a time of industry and big cities, like London, had a tremendous amount of jobs and not enough adults so they used the kids. Children would work from 12 to 18 hours a day in these harsh conditions that respiratory problems started to arise. Children were either permanently injured or died.
London at the time was completely filthy due to the lack of the sewage system back in the 19th century. Diseases and illnesses spread rampantly through the large communities and the people would only live unto 25 years old due to their horrible living conditions that they were placed in. Many young children died and those who did not, barely survived.
