The 1881 census can be searched by occupation. It shows that 96 individuals have given "Unfortunate" as their occupation. All are female, all unmarried or widowed; some have children, others do not. All but a handful live as lodgers, boarders or visitors, or as head of a household which usually contains other women with the same occupation. The lodgers/boarders etc are often in small or medium-sized lodging houses, often in the dock areas of East London and Liverpool, though some are in other places such as Birmingham, Reading and Newcastle. Some of the boarding houses contain other women (and sometimes men) with different occupations - hawkers, travellers, charwomen etc. Others of the houses contain only women with occupation "Unfortunate".
Among the handful of the 1881 Unfortunates who are not in lodging houses are:
Sarah Thomas, an 18-yr-old living in the household of her father (a shipwright) and mother (no occupation) in the East London docks area. A 19-yr old female lodger in the household also gives her occupation as Unfortunate. Next door is a lodging house in which the 40-yr-old head and her two lodgers are all Unfortunates.
Emily Cooney, a 25 yr old inmate in the Westminster workhouse with a 1-day-old baby. The other female inmates, some of whom are also unmarried mothers, give their occupations as servants, charwomen etc. (or no occupation) - some are deaf or imbeciles according to the far right hand column - but Emily is the only Unfortunate I can see there and has no disabilities listed.
C.H., a 41 yr old female patient in the Middlesex County Lunatic Asylum. The patients are all either lunatics or imbeciles in the far right-hand column. So far as occupations are concerned, some of them are charwomen or labourers' wives; I can see at least one Pauper and many with no occupation, but C.H. (a lunatic) is the only one I can see whose occupation is listed as Unfortunate.
Patricia Cornwell, in her book about Jack the Ripper, explains the use of the term Unfortunate to denote a prostitute (I don't have it to hand at this moment) - sadly, Jack the Ripper preyed on these vulnerable women.
