We focus on four complex health issues more prevalent in urban areas
With the Social Progress Imperative, we've developed the first neighbourhood level, health-focused social progress index of its kind.

Data and analytics
We have used the Simpson’s Diversity Index (SDI) methodology to measure community diversity and what it means for Lambeth and Southwark.
Our work focuses on improving health equity across Lambeth and Southwark. Understanding the diversity of our neighbourhoods is key to this.
Our research has shown that some minority ethnic groups face the biggest health inequalities. In our boroughs, the proportion of people with two or more long-term conditions is higher among Black communities.
The 2021 Census shows that the population in England increased by 7% to 56.5 million in the last decade, and has become more ethnically diverse. In 2011, 10.7 million people reported being from a “non White-British” ethnic group, while in 2021 this number increased by 39% to almost 15 million. People identifying as “Other White” (all White people who are not White-British, Irish, Gypsy or Irish Traveller) accounted for the largest share of growth in the total population.
Lambeth and Southwark have also become more ethnically diverse. 63% of the population now identify as a “non White–British” ethnic group. The number of people who opted to write-in their ethnicity increased by 150% to 31,704. Within this group, almost half self-identified as Hispanic or Latin American.
Analyses of the ethnic diversity of neighbourhoods in England shows that ethnic diversity is a characteristic of many urban areas. This does not mean that all urban areas are ethnically diverse, but that all the areas that are very ethnically diverse are urban. 90% of neighbourhoods classified as rural have a diversity index below 0.2, and only a handful of them have an index greater than 0.5.
Out of 333 Local Authorities in England, Lambeth and Southwark are the 20th and 15th most ethnically diverse.
18 of the 20 most diverse Local Authorities are in London.
London boroughs have a higher diversity than most in England. But levels of diversity vary within their smaller neighbourhoods. For example, all neighbourhoods in Newham are very diverse (SDI> 0.8), whilst other boroughs may be very diverse as a whole but show more variation at the neighbourhood level.
All neighbourhoods in Lambeth & Southwark have a higher diversity than England (SDI=0.451). Streatham Vale in Lambeth is the most diverse (SDI = 0.88) and Herne Hill & Dulwich Park in Southwark is the least diverse (SDI= 0.55).
Areas can have the same diversity index score but a very different ethnic composition. The most diverse local authorities have a very different mix of ethnic groups. For example, Westminster and Redbridge have a very similar Diversity Index score. But just under 50% of residents in Redbridge are from Asian backgrounds, compared to only 17% of residents in Westminster.
A quarter of the population in Lambeth and Southwark is from a Black ethnic group, the highest proportion after Lewisham. But both boroughs have a smaller percentage of people from Asian background compared to other very ethnically diverse areas.
In 2021, ethnic diversity in Lambeth & Southwark, as for the majority of London boroughs, was higher amongst the youngest population. 70% of residents under 24 in our boroughs are from “non White-British” ethnic groups.
Generally, the oldest age group is the least diverse. Yet this is not the case in Lambeth and Hackney. In both of these boroughs, the least diverse age group is 25 – 34 years.
To improve health equity, we have to understand ethnic diversity and how the urban environment affects people differently. Both Lambeth and Southwark have incredibly ethnically diverse populations. Therefore, it is essential that we consider ethnicity, and use this in intersection with other measures when trying to understand the population.
We will use this data to ensure initiatives are tailored to our population, in the programmes we develop and the partners we work with.
The census is undertaken by the Office for National Statistics every 10 years. It gives us a picture of all the people and households in England and Wales.
The 2021 Census asked respondents to choose which ethnic groups or backgrounds best describes them from a list of 19 options. There was also an additional option to add it in writing.
We have used the Simpson’s Diversity Index (SDI) methodology to measure community diversity and what it means for Lambeth and Southwark. The index reflects the probability that any two individuals selected at random will belong to a different ethnic group. It takes values between 0 and 1; a high score indicates higher diversity.

Health effects of air pollution
For the first time since August 2020, a high pollution warning has been issued for London. We explore what the major causes of air pollution are in London.
