Hundreds are a land unit unique to Delaware, and smaller than a county.  New Castle Hundred in the 1863 Beers Atlas is shown running from Red Lion to Wilmington, bordered on the west by the White Clay Creek.

Average Family Size was small:  2.49 in 1850,  3.14 in 1870.  These numbers are based on counts of different last names in families as defined by the census enumerator, and includes numerous single individuals as 'families'.  However there were large families: 39 families had 8 or more individuals with the same last name living in one house.  The family size from the 2000 census is unchanged: 3.14

Birthplace  About 70% of New Castle residents in 1850 and 1870 were born in Delaware. Ireland was the next most common place of origin in 1870, and a close third in 1850 (5.6% and 3.4% respectively),  followed by the three adjacent states.  England was a distant 5th or 6th.  Complete list  In 2000 the percent foreign born is still about the same, about 6%, though the countries of origin have  changed as well as the place of residence.  Only about 1% of the residents of the Town of New Castle are foreign born; however the percentage in areas to the west, north and south vary from 5 to 10% .  The most common country of origin in 2000 was ....

Occupations in the Town of New Castle
 
  In 1870, there were 150 occupations listed for the 1915 individuals.  The most common is "At Home" which are all children with the exception of 8 people over 60 years old.  The next most common is "Keeping House", which includes both housewives and 16 housekeepers (for example, Sara Mason, who was keeping house for her husband, and Samuel Guthrie, the owner of 30 The Strand).  The real and personal values of the housekeepers and those "without occupation" is quite high, since it includes wealthy men and their widows, such as William Couper (owner of the Read House), and Mary Read.
    New Castle was now a mill-oriented community-- the third most common job outside of the home was in a cotton mill.  Presumably the workers (evenly divided between men and women) worked in the Triton Mills, finished just after the Civil War.  Some of the occupations in the full list appear unusual: gold beater

Occupations in New Castle Hundred
   
The distribution of occupations was quite different outside of the town in the very much more rural Hundred: ten times as many people were farmers or worked on a farm, were without occupation, or lived at home as the next most common occupation: domestic worker.  

OCCUPATION Number Real Value (Avg) Personal Value (Avg)
At Home 542   3427
Works on farm 374 867 7141
Keeping House 275 8833 2217

Wealth
   
The wealthiest individuals in 1870 (in terms of real property) include Dr. Lesley, the owner of the just-built mansion (now the Deemer Mansion), Elihu Jefferson, owner since the 1820's of the largest house on the Strand and William Couper, owner of the Read House.
   The distribution is of course very uneven -- all the people in 57 of the 151 occupations listed zero real wealth.  This must be partially an artifact of data collection.  Assuming that personal wealth includes salary,  people in 90/151 occupations also list no personal wealth, even though their jobs -- watchman, factory worker, or school teacher must have been paid.  50 Wealthiest

Wealth --farm vs non-farm, Town vs Hundred  in 1870
