There clearly was just a positive change out of 4

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.

Classification (NS-SEC)

Adopting the towards regarding current manage classifying the brand new public group of tweeters of profile meta-studies (operationalised inside context since the NS-SEC–find Sloan et al. for the complete methods ), i incorporate a category recognition algorithm to the studies to analyze if particular NS-SEC organizations be more otherwise less inclined to permit location qualities. Although the class identification equipment isn’t finest, previous research shows that it is specific inside the classifying specific teams, significantly masters . General misclassifications is actually associated with work-related terms together with other significance (such as ‘page’ or ‘medium’) and you will work which can also be termed hobbies (particularly ‘photographer’ otherwise ‘painter’). The possibility of misclassification is an important limit to look at whenever interpreting the outcomes, however the very important area is the fact i’ve no a priori cause for believing that misclassifications wouldn’t be at random marketed around the people with and you may without venue attributes permitted. With this in mind, we are really not such looking for the overall signal regarding NS-SEC communities from the data since the proportional differences when considering location enabled and non-let tweeters.

NS-SEC is harmonised along with other Eu measures, nevertheless field identification product was created to get a hold of-up British work merely also it shouldn’t be applied outside of perspective. Earlier research has known British profiles playing with geotagged tweets and bounding packages , however, while the function of it paper would be to compare that it classification along with other non-geotagging profiles i decided to have fun with go out region just like the a good proxy to own venue. The newest Twitter API brings an occasion zone career for every representative and also the following analysis is bound to help you pages associated with you to of these two GMT areas in the uk: Edinburgh (n = 28,046) and you may London area (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.
