Index of Multiple Deprivation (IMD) 2019
The index of multiple deprivation (IMD) score measures deprivation
levels by area, with higher scores indicating greater deprivation.
Scores are calculated using factors including income, employment,
education, health, crime, housing barriers, and living environment.
Greater deprivation is strongly linked to poorer health outcomes.
Each Lower Super Output Area (LSOA) in England receives an IMD score
and is ranked from most to least deprived. LSOAs are commonly grouped
into deciles or quintiles to provide clearer deprivation comparisons
across areas.
An LSOA is a small geographical area with typically 1,000-3,000
people, designed as a consistent population unit for statistical
comparison.

Distribution of Tower Hamlets Network 1 PCN’s
population by IMD decile
Each decile represents a tenth of all LSOAs, with the first decile
being in the most deprived 10% and the tenth decile being in the least
deprived 10% in England.
Decile 1 and 2 together equate to the ‘Core 20’ population, which is
a focus for health inequalities work across the NHS.

Summary IMD score weighted by the distribution of all the PCN’s
registered patients
Here we derive a single deprivation score* for the PCN population
using the distribution of registered patients with recorded home
addresses. This allows us to compare and rank PCN patient populations by
relative deprivation.
Tower Hamlets Network 1 PCN has a
population-weighted IMD 2019 score that places it at position 4 out of 7
PCNs in Tower Hamlets, where most deprived would equal 1.
Across NEL ICB the PCN is at position 15 out of 48 PCNs. On a
national basis, the score equates to IMD decile 3 in England.
The ‘National IMD decile equivalent’ indicates the relative position
within England, with 1 being the most deprived 10% and 10 being the
least deprived 10% of areas.
*These PCN population weighted deprivation scores follow the
method described on pages 69 and 70 of Appendix A in the English Indices of Deprivation 2019: research
report.

Extent of deprivation in the Tower Hamlets Network 1 PCN
population
This extent of deprivation measure calculates the
proportion of a local population living in the most deprived areas
nationally. It improves upon the basic “most deprived 10%” measure by
eliminating sharp cut-offs where areas just outside the top 10% receive
no weight.
Instead, it uses graduated weighting covering the most deprived 30%
of areas nationally. PCN patients in the most deprived 10% each receive
full weight (1.0), while those in the 11th-30th percentile receive
sliding weights from 0.95 down to 0.05. Areas outside the most deprived
30% receive zero. This provides a more nuanced view of deprivation,
capturing the range of deprivation levels within disadvantaged
areas.
Across NEL ICB, PCN values for the extent of the most deprived range
from 0.5% to 58.8%, with a median of
27.1%.

Extent of deprivation by ethnicity
Extent of deprivation in Tower Hamlets Network 1 PCN GP registered
population by ethnicity: which ethnic groups have a larger proportion
living in areas of higher deprivation.
