Read profile summary

Group profile

This Group is often found in less central parts of London and other major towns and cities. Adults are more likely than the Supergroup average to have never been married and are typically aged less than 45 years. Many have young dependent children and individuals may have been born in Africa. There are many members identifying with a Black ethnic group, with the other ethnic groups (as listed in the glossary) also represented, though Chinese less so. Accommodation in flats, frequently socially rented, is common in these neighbourhoods. Part time employment is also common, and work is often in elementary occupations, while unemployment is also the highest within this Supergroup.

Wider pattern

Young adults, many of whom are students, predominate in these high-density and overcrowded neighbourhoods of rented terrace houses or flats. Most ethnic minorities are present in these communities, as are people born in European countries that are not part of the EU. Students aside, low skilled occupations predominate, and unemployment rates are above average. Overall, the mix of students and more sedentary households means that neighbourhood average numbers of children are not very high. The Mixed or Multiple ethnic group composition of neighbourhoods is often associated with low rates of affiliation to Christian religions. This Supergroup predominates in non-central urban locations the UK, particularly within England in the Midlands and the outskirts of west, south and north-east London.

Flatted accommodation is less dominant than elsewhere in the Supergroup.

Wider London pattern

A Supergroup embodying London's diversity in many respects, apart from low numbers of residents identifying as of Bangladeshi, Indian, Pakistani or Other (non-Chinese) Asian ethnicity. There is lower than average prevalence of families with dependent children, while there are above average occurrences of never-married individuals and single-person households. The age distribution is skewed towards younger, single residents and couples without children, with many individuals identifying as of mixed or multiple ethnicity.

Individuals typically work in professional and associated roles in public administration, education or health rather than in elementary occupations in agriculture, energy, water, construction or manufacturing. Incidence of students is slightly below average. Individuals declaring no religion are more prevalent than average and non-use of English at home is below average.

Meaning and origin of Lach

The surname LACH is believed to have originated in Poland. It is a regional name that derived from the Polish word "lach," which referred to a Pole or someone from Poland. The name can be traced back to the 13th century in historical records.

The earliest known bearer of the name was a Polish nobleman named Lach who lived in the late 13th century. He was mentioned in a manuscript from the year 1278 that documented land ownership in the region of Poznan, which was part of the Kingdom of Poland at that time.

In the 14th century, the name appeared in the form "de Lach" in records from the town of Krakow. This Latin variation likely referred to someone from the village of Lach or a person whose family originated from that area.

One of the earliest known people with the surname LACH was Jan Lach, a merchant who lived in the city of Gdansk in the late 15th century. He was mentioned in a trade document from the year 1487 as having conducted business with merchants from the Hanseatic League.

Another notable bearer of the name was Piotr Lach, a Polish soldier who fought in the Polish-Muscovite War of 1609-1618. He was recognized for his bravery in battle and was awarded lands in the region of Podlasie after the war.

In the 17th century, the name LACH appeared in records from the town of Przemysl, which was part of the Polish-Lithuanian Commonwealth at the time. A family by the name of Lach owned a farm in the area, and their descendants continued to live in the region for several generations.

One of the most famous individuals with the surname LACH was Waclaw Lach, a Polish poet and writer who lived from 1664 to 1728. He was known for his satirical works that criticized the nobility and the political system of the Polish-Lithuanian Commonwealth.

During the 19th century, the name LACH was found in various regions of Poland, including the areas of Galicia, Silesia, and the Grand Duchy of Posen. Some notable people with this surname from that period include Franciszek Lach, a Polish painter born in 1820, and Jozef Lach, a Polish composer born in 1856.
