Census counts are people who LIVED in Isle of Anglesey and were in work in that occupation in March 2021. They are not jobs located in the area, and they are not adverts. They are also published for a group of related occupations (minor group 213) rather than for a single job title, because that is the finest detail the census publishes at local authority level. That group covers software developers, IT managers, architects, analysts, cyber security specialists and IT project managers.

Job counts are employee jobs that exist in Isle of Anglesey, counted once a year by a survey of businesses. They are not adverts, and they are not a measure of how many roles are open. They count a different population from the census figures above, so the two are never divided by one another.

The pay figure for this occupation covers Wales, not Isle of Anglesey on its own. ONS does not publish pay by occupation at local authority level at all, so every area in the region shares this number and no narrower published figure exists.

The area pay figure covers every occupation in Isle of Anglesey together. It is the only pay figure published for the area itself, and it is not a pay figure for this role.

Medians, not averages. Half the jobs counted paid less than the figure shown. What any individual advert pays is on the advert.

The software developer role

Writing software that other people depend on, and staying responsible for it once it is running. Most of the job is reading existing code, understanding why it is the way it is, and changing it without breaking anything.
