Household Occupancy
MigrationFindings:
AdamThe central region of the borough has the highest concentration of people who have lived in the UK for less than 2 years as well as the area with most households deemed as overcrowded. 23English Proficiency Occupation
Findings: Pairing Social Vulnerability Factors
AdamThe Northern central part of the borough have concentrations of non-English and low skilled workers.24UnemploymentDisability
Findings: Pairing Social Vulnerability Factors
AdamAreas with higher portions of the populations with a disability/ long term health problem also tend to have higher unemployment. Disability and long term health problems must play an important factor in employment.25
English Proficiency MigrationFindings: Pairing Social Vulnerability Factors
AdamThe central of the borough has a high concentration of non-English speaking immigrants. But the areas of lowest English Proficiency do not align with the highest areas of migration meaning those non-English speakers in the northern section of the highlighted circle have been in the borough for longer than 2 years and more likely to be better established in their communities26CompositesPublic Health
