Vape Shops Per Capita
We used the Google Maps API to scrape data from their service on the number of establishments that appeared for ‘vape in [location name]’. The results were not geographically exclusive to the towns, but rather the number of vape shops in the local area a person could reasonably get to.
The number of vape shops in the area was then divided by the population of the local area to give a number of vape shops per population. Population data was taken from the latest available from the Office of National Statistics: https://www.nomisweb.co.uk/default.asp
Quality of Vape Shops
We used the Google Maps API to scrape data from their service on the number of and scoring of reviews for vape shops in the local area of each town. These scores were then averaged vs the total number of shops that had reviews. Shops that had no reviews were excluded from the averaging process.
Search Interest in Vape
We used Google Trends to observe which UK towns had the most proportionate search interest in the keyword ‘vape’. Swindon has the most because out of all the towns in the UK they search for vape more than anything else, proportional to the other towns.
NHS Spend Per Quitter
We used the latest NHS data for their official ‘cost per quitter’. We included costs for pharmacotherapies. https://digital.nhs.uk/data-and-information/publications/statistical/statistics-on-nhs-stop-smoking-services-in-england/april-2018-to-december-2018
The NHS states that: “The expenditure/cost per quitter data shown in this table is calculated by dividing the total spend on smoking cessation services in the year by the number of successful quitters (self-reported). From 2011/12 onwards, organisations have been advised to only include monies spent on smoking cessation activity, not wider tobacco control measures. There is some evidence that in practice there may be a lack of standardisation in terms of the scope of expenditure items included in some organisation’s returns; this means figures may not always be calculated on a comparable basis locally.”
% Change in Quit Rate
To calculate the change in quit rate change, we simply used the following formula:
(2018 value - 2009 value)/2009 value = percentage increase
To allow more direct comparisons between different data sets, we then normalised some of our data sets. This process involved finding the highest and lowest values, and then ranking each city/region accordingly out of 10.
For example, Newcastle under Lyme has the most vape shops per capita, at 3.78 shops per 10,000 residents, so it gets a score of 10. In the middle of the list is Thanet which as 1.90 shops per 10,000 residents, so this location gets a score of 5.03. The lowest density of vape shops was Waltham Forest with just 0.04 shops per 10,000; so this location receives a score of 0.00. All other cities are ranked within this scoring system accordingly.
