The rapid industrialization of Russia also resulted in urban overcrowding and poor conditions for urban industrial workers (as mentioned above). Between 1890 and 1910, the population of the capital, Saint Petersburg, swelled from 1,033,600 to 1,905,600, with Moscow experiencing similar growth. This created a new proletariat which, due to being crowded together in the cities, was much more likely to protest and go on strike than the peasantry had been in previous times. In one 1904 survey, it was found that an average of sixteen people shared each apartment in Saint Petersburg, with six people per room. There was also no running water, and piles of human waste were a threat to the health of the workers. The poor conditions only aggravated the situation, with the number of strikes and incidents of public disorder rapidly increasing in the years shortly before World War I. Because of late industrialization, Russias workers were highly concentrated. By 1914, 40% of Russian workers were employed in factories of 1,000+ workers (32% in 1901). 42% worked in 100-1,000 worker enterprises, 18% in 1-100 worker businesses (in the US, 1914, the figures were 18, 47 and 35 respectively).. How many more people were in Saint Petersburg in 1910 than in 1890?
