Nothing can convey an idea of the material blessings which resulted from this better than a glance at the vital statistics relating to Willenhall. The death-rate per thousand—
| From 1845 to 1851 was | 29 |
| ,, 1851 ,, 1860 ,, | 26.8 |
| ,, 1861 ,, 1870 „ | 23.8 |
| „ 1891 ,, 1900 ,, | 20.2 |
| „ 1901 „ 1906 „ | 16.9 |
It was not till 1866, however, that the Board appointed its first medical officer of health, Dr. Parke. He was shortly afterwards succeeded by Mr. William Henry Hartill, and upon his death, in 1888, the present medical officer of heath, Dr. J. T. Hartill, was appointed. The chief executive officers in succession have been Mr. E. Wilcox (who was not a solicitor), Mr. John Clark, and the present clerk, Mr. Rowland Tildesley, appointed in 1894.
In the meantime the population, particularly in the newer outlying districts, had been growing rapidly. The population of Willenhall at the first national census in 1801 was only 3,143, and the growth in the early decades was slow, as these figures disclose:
| In 1811 the population was | 3,523 |
| ,, 1821 | 3,965 |
| ,, 1831 | 5,834 |
| „ 1841 | 8,695 |
| ,, 1851 | 11,933 |
| ,, 1861 | 17,256 |
With the growth thus becoming so rapid, it was thought desirable, in 1872, to erect Short Heath into a separate Sanitary Authority. The area allotted to the Short Heath Board of Health was that north of the Birmingham Canal, but the village of Short Heath itself remained part of the Township of Willenhall.
The census returns for Willenhall, minus Short Heath, have
| 1871 it had a population of | 15,903 |
| 1881 | 16,067 |
| 1891 | 16,851 |
| 1901 | 18,515 |
After the passing of Sir H. H. Fowler’s Local Government Act in 1895, both authorities became Urban District Councils. Short Heath then as a separate township had its area extended to take in Short Heath village, with New Invention, Lanehead, Sandbeds, Lucknow, Fibbersley, in addition to the former Local Board district, together with a slice from the old Wednesfield Local Board district added on its Essington side.
No part of what used to be called Stow Heath was in Willenhall Township, the extreme western boundary of the latter being Stow Heath Lane.
