This record contains data used in the study titled: "Ethnic Density and First Episode Psychosis in the British Pakistani Population: Findings from the East Lancashire Early Intervention Service".

Two STATA datasets (.dta files) are provided: one containing only the FEP (first episode psychosis) sample ("DATA TABLE FEP only.dta"), and another containing both FEP and ARMS (At-Risk-Mental-States) samples ("DATA TABLE FEP + ARMS.dta").

Data was collected by East Lancashire Early Intervention Service between 2012 and 2020. All accepted referrals relating to patients that self-identified as either White or Pakistani within that time period are included. 

Both datasets include the same variable list:
LSOA - lower super output area code
LSOAName - string name of each LSOA
IMD - 2015 index of multiple deprivation score for each LSOA
EthnicDensity_Pakistani - % of residents who identify as Pakistani within each LSOA, taken from the 2011 Census in England & Wales 
EthnicDensity_White - % of residents who identify as White within each LSOA, taken from the 2011 Census in England & Wales 
EthnicityWhite0 - binary variable where 0 indicates white individual ethnicity and 1 indicates Pakistani individual ethnicity
Genderf0 = individual sex, where 0=female and 1=male
AgeCategory - age category for each individual where 0=0-24, 1=24-49, 3=50-64
PopulationAtRisk - total population within each LSOA, stratified by ethnicity, sex, and age category, using data from the 2011 Census in England and Wales
PersonYears - Population at risk multiplied by the study time period (exposure variable)
Count - total incidence of FEP/FEP+ARMS (primary outcome variable)

Two stata .do files are also included for use with each corresponding dataset ("Analysis FEP Only.do" and "Analysis FEP+ARMS.do"), which contain the code used to carry out the data analyses.
