Fig 1 illustrates the two distributions of age for those who do enable location services and those who do not. There is a long tale on both, but notably the tail has a less steep decline on the right-hand side for those without the setting enabled. An independent samples Mann-Whitney U confirms that the difference is statistically significant (p<0.001) and descriptive measures show that the mean age for ‘not enabled' is lower than for ‘enabled' at and respectively and higher medians ( and respectively) with a slightly higher standard deviation for ‘not enabled' (8.44) than ‘enabled' (8.171). This indicates an association between older users and opting in to location services. One explanation for this might be a naivety on the part of older users over enabling location based services, but this does assume that younger users who are more ‘tech savvy' are more reticent towards allowing location based data.

Fig 2 shows the distribution of age for users who produced or did not produce geotagged content (‘Dataset2′). Of the 23,789,264 cases in the dataset, age could be identified for 46,843 (0.2%) users. Because the proportion of users with geotagged content is so small the y-axis has been logged. There is a statistically significant difference in the age profile of the two groups according to an independent samples Mann-Whitney U test (p<0.001) with a mean age of for non-geotaggers and for geotaggers (medians of and respectively), indicating that there is a tendency for geotaggers to be slightly older than non-geotaggers.

Class (NS-SEC)

Following the into away from current work with classifying this new public category of tweeters of character meta-study (operationalised within this framework because the NS-SEC–select Sloan ainsi que al. into the complete methodology ), we pertain a course identification formula to our research to analyze if or not specific NS-SEC teams be more otherwise less likely to want to permit venue functions. While the group identification product isn’t finest, prior studies have shown it to be direct within the classifying particular groups, significantly benefits . General misclassifications was of work-related conditions along with other definitions (such ‘page’ or ‘medium’) and you may jobs that will additionally be called welfare (particularly ‘photographer’ or ‘painter’). The possibility of misclassification is a vital restrict to consider when interpreting the outcomes, although important area is that i’ve no a good priori reason for believing that misclassifications would not be at random delivered all over those with and you can instead venue characteristics let. Being mindful of this, we are not such trying to find the general signal of NS-SEC teams on study since proportional differences between venue let and you may low-allowed tweeters.

NS-SEC will likely be harmonised together with other Western european steps, however the occupation identification device is made to select-right up Uk work simply therefore should not be used exterior for the framework . Previous studies have recognized British users playing with geotagged tweets and bounding packets , however, given that purpose of it papers is to try to evaluate this category together with other non-geotagging pages i decided to have fun with day area since the a proxy having area. The brand new Twitter API will bring a period zone job for each and every representative plus the following research is restricted so you can profiles from the that of these two GMT zones in the uk: Edinburgh (n = twenty-eight,046) and London (n = 597,197).

There is a statistically significant association between the two variables (x 2 = , 6 df, p<0.001) but the effect is weak (Cramer's V = 0.028, p<0.001). 6% between the lowest and highest rates of enabling geoservices across NS-SEC groups with the tweeters from semi-routine occupations the most likely to allow the setting. Why those in routine occupations should have the lowest proportion of enabled users is unclear, but the size of the difference is enough to demonstrate that the categorisation tool is measuring a demographic characteristic that does seem to be associated with differing patterns of behaviour.
