In St. George-in-the-East it had been brought about “by the extension of warehouses and the demolition of insanitary property.” In St. Martin-in-the-Fields it was “due to many former residents having removed to the country, and to the demolition of so many houses for improvements.” In the Strand to the fact that the district was becoming like all the central parts of London, “a business, as distinguished from a residential district.” The Vestry of St. James’ reported that “buildings formerly occupied as dwellings were being replaced by warehouses and business premises commanding a higher rent. As the centre of trade extends, this condition of things must be expected to continue, just as the increasing volume of trade has converted the City of London at night from a populous place to little more than a city of caretakers,” and they drew attention to the “enormous number of people engaged in business in the parish during the day time who resided elsewhere.”

On the south side of the river the same story was told. The Medical Officer of Health for Lambeth remarking in his report that—

“The displacement of population from the central districts of Lambeth, and the settlement of population in those districts which are situated in the outer ring, or on the circumference of the inner, is a part of a greater movement which affects the whole metropolitan area.”

The census of 1891 is specially memorable by the fact that for the first time a mass of most valuable information was obtained which was wholly new, and which threw a blaze of light upon the condition of the housing of the population of London.

For the first time full details were obtained and published as to the numbers of the people living in tenements of less than five rooms and the numbers and character of the tenements they lived in.

A tenement was defined as “any house or part of a house separately occupied either by the owner or by a tenant.”

These tenements were classified into those of one room, two rooms, three rooms, and four rooms; and the number of persons inhabiting each of these classes of tenements was given.

The nearest approach to information of this sort had been given by Mr. Marchant Williams in 1884, but it was only for a particular area in London. The information now given related to the whole of London.

The total number of tenements in London in 1891 was stated to be 937,606.
