South Hadley prospered briefly as a manufacturing centre (producing textiles, paper, buttons, and leather) during the 1830s, but it is now primarily a residential locality with a service-based economy.
If there were multiple residential locality codes for one person, then the residential locality was determined by the highest frequency of recorded visits or hospitalisations.
Key socio-demographic status variables included age, gender, marital status, highest education level attained, occupation, residential locality and household income level.
During data cleaning, we modified 25% of the 2011 and 5% of the 2012 line list values for residential locality, age, and date parameters (Table 3).
Therefore, Israeli Arabs can be identified only by their residential locality or (as in large mixed cities such as Nazareth) sub-district data, recorded by the National Census [ 21].
Although 11% of the population cohort had missing socioeconomic status or residential locality data, there was no difference in survival for those excluded; the findings are therefore representative of outcomes for the WA population.
We obtained hazard ratios and associated 95% confidence intervals after adjusting for age, sex, indigenous status, residential locality, socioeconomic disadvantage, admission type, hospital type, length of hospital stay, calendar period of ADR, Charlson comorbidity index, and drug categories.
The results extend prior work by showing that not only do clusters differ by age, gender, marital status, education and income but they also differ in terms of work status and residential locality, which explained unique variance in membership even after controlling for all other factors.
