Birth and Death
Rate
The Birth rate per 1,000 per annum—Census 1891—
was 34.14; Population estimated—was 31.97. The Death
rate per 1,000 per annum — Census 1891 — was 18.15;
Population estimated—was 16.98. The corrected Death rate
(i.e., taking away the 12 Deaths occuring in Orsett Union
among persons not belonging to the District, and adding the
2 occuring in Brentwood Asylum belonging to this District)—
Population estimated—was 16.34. The Birth rate 31.97
was 2.50 below that of the last 14 years, and 3.66 below that
of last year. The corrected Death rate 16.34 was low, and
was .49 below that of the last 14 years, and was 2.21 below
that of last year.
Infant Mortality
Infant mortality, or the number of Deaths under 1 year
was 60, and was at the rate of 3.90 per 1,000, or measured by
the proportion of Deaths to Births registered was 122 to the
1,000, these Deaths are 1.23 and 21 respectively below those
of last year, and are moderate.
Zymotic Disease
The number of Deaths from the principal Zymotic
Diseases was 45, and the Death rate per 1,000 per annum
was 2.92. This Death rate is high, and is .75 above the
average for last 10 years, and .80 above that of last year.
The increase being chiefly due to Deaths from Diphtheria,
Membranous Croup, Puerperal Fever, and Diarrhœa.
Number of Persons
per acre,
and number
per Inhabited
House.
2.6 acres to 1 person. In no part is there any great
overcrowding of houses. I do not know the number of
inhabited houses in the district, but estimate the number of
inhabitants per house at between 5 and 6.
Chief Geological
Features
The Geological formation underlying the district is
chalk, which crops out at Grays and Stiffoid. Thanet sands
occur on the uplands of Aveley, Grays, Little Thurrock,
Chadwell-St.-Mary and West Tilbury. Woolwich beds at
parts of Orsett, South Horndon-on-the-Hill (Pump Street),
and North Stanford-le-Hope. London Clay crops out at
Bulphan and the adjoining parts of Orsett, Horndon-on-theHill
and Laindon Hills, Corringham and Fobbing. Patches
of Bagshot beds occur at Laindon Hills (the top) and Dry
Street, Fobbing. Brick Earth and Gravel at various places.
Alluvial deposit on the whole South border of District and
greater part of the Eastern boundary, and at Orsett and
Bulphan Fens.
Chief Physical
Features
The District is for the most part flat and low. The
only Hill of importance is Laindon Hills (in the NorthEast),
385-ft. high. It is bounded on the South and East
(in great part) by the River Thames. Bordering the Thames
are Marsh lands, varying in width from a few yards (at
Purfleet) to 1½ miles on the South-East and East. At the
North edge of the Marshes the land rises to a height of
100-ft. or so, the greater part of the District being a table
land, which gradually falls to the North.
