The greater reliability of food supplies was a factor in the decline of urban
death rates. Even more important were the gains in urban sanitation, as well
as measures such as inspection of housing. Reformers, including enlightened
doctors, began to study the causes of high death rates and to urge
remediation. Even before the discovery of germs, beliefs that disease spread
by "miasmas" (noxious forms of bad air) prompted attention to sewers and open
garbage; Edwin Chadwick led an exemplary urban crusade for underground sewers
in England in the 1830s. Gradually, public health provisions began to cut
into customary urban mortality rates. By 1900, in some parts of
Western,Europe life expectancy in the cities began to surpass that of the
rural areas. Industrial societies had figured out ways to combine large and
growing cities with population growth, a development that would soon spread
to other parts of the world.
