Neighbourhood profile for Caslin

Modern surname records can be compared with neighbourhood classifications. For Caslin, this points to the kinds of places where the surname is most concentrated today.

These neighbourhood labels describe areas, not individual people. They are useful because surnames often cluster through family history, migration, housing patterns and local work. A surname can be strongest in one type of neighbourhood even when people with that name live across the country.

The UK classification gives the national picture. The London classification is more specific to the capital, where housing, age profile, tenure and population mix can look quite different from the rest of the UK.

UK neighbourhood type

UK Output Area Classification

Supergroup

Semi- and Un-Skilled Workforce

Group

Established but Challenged

Nationally, the Caslin surname is most associated with neighbourhoods classed as Established but Challenged, within Semi- and Un-Skilled Workforce. This does not mean every Caslin household fits that profile, but it gives a useful signal about where the modern surname distribution is strongest.

Read profile summary

Group profile

Many households in these neighbourhoods comprise separated or divorced single parents with dependent children. Residents are typically born in the UK, and these neighbourhoods have relatively few members of ethnic minorities. The prevalence of children, their parents and those at or above normal retirement age, suggests neighbourhood structures may be long-established. Levels of unpaid care are high, and long-term disability is more common than in the Supergroup as a whole. Use of the social rented sector is common, often in terraced houses. Levels of overcrowding are above the Supergroup average. Unemployment is high, while those in work are employed in elementary occupations such as caring, leisure and customer services. Many residents have low level qualifications. Neighbourhood concentrations of this Group are found in the South Wales Valleys, Belfast, Londonderry and the Central Lowlands of Scotland.

Wider pattern

Living in terraced or semi-detached houses, residents of these neighbourhoods typically lack high levels of education and work in elementary or routine service occupations. Unemployment is above average. Residents are predominantly born in the UK, and residents are also predominantly from ethnic minorities. Social (but not private sector) rented sector housing is common. This Supergroup is found throughout the UK’s conurbations and industrial regions but is also an integral part of smaller towns.

London neighbourhood type

London Output Area Classification

Supergroup

Professional Employment and Family Lifecycles

Group

Established Homeowners with Children

Within London, Caslin is most associated with areas classed as Established Homeowners with Children, part of Professional Employment and Family Lifecycles. This gives the surname a London-specific profile rather than forcing the capital into the same pattern as the rest of the country.

Read profile summary

Group profile

These predominantly British-born residents are typically married/in civil partnerships and own the properties in which they are raising their children. Parents are typically over 45, and many other residents are beyond normal retirement age. Detached and semi-detached houses predominate and multiple car ownership is common.

Wider London pattern

These neighbourhoods house people of all ages, predominantly of White British or European extraction. Resident turnover is low. Religious affiliation is less common than average and tends to be Christian if expressed. Homeownership, typically of terraced houses, is common but use of the social rented sector is not. Employment is typically in professional, managerial and associate professional or technical occupations. There are few full-time students. Level 4 qualifications are common. More households lack dependent children than have them which, considered alongside low levels of crowding and over-all age structure, indicates that many households may be post child-rearing and in late middle age. Incidence of disability is low, as is residence in communal establishments.

Meaning and origin of Caslin

The surname Caslin is of Irish origin and is believed to have originated in the County Cork region of Ireland. It is derived from the Gaelic word 'Ó Caisil', which means 'descendant of Caiseal'. Caiseal was a personal name meaning 'circular fort' or 'stone fort'.

In the 16th century, the name appeared in the Fiants of the Tudor Sovereigns, a record of official documents issued by the English monarchy during the reign of the Tudor dynasty. These records mention a John Caslin who was granted lands in County Cork in 1584.
