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.
Category (NS-SEC)
Pursuing the for the out-of current focus on classifying the fresh personal category of tweeters off profile meta-studies (operationalised inside context since the NS-SEC–look for Sloan mais aussi al. to the complete methodology ), we pertain a course identification formula to your investigation to research if or not specific NS-SEC communities much more otherwise less likely to enable place characteristics. Although the classification identification product is not przeglÄ…d bicupid finest, earlier research shows it to be accurate within the classifying certain teams, somewhat benefits . General misclassifications was associated with the work-related terms and conditions with other significance (such as for instance ‘page’ or ‘medium’) and you may jobs that will additionally be termed appeal (for example ‘photographer’ or ‘painter’). The possibility of misclassification is an important limitation to consider whenever interpreting the results, nevertheless the extremely important part would be the fact i’ve zero a good priori cause for convinced that misclassifications wouldn’t be randomly distributed all over individuals with and you will as opposed to place attributes enabled. Being mindful of this, we are not much seeking the overall symbol away from NS-SEC communities about data while the proportional differences when considering venue let and you may low-allowed tweeters.
NS-SEC is going to be harmonised with other Western european actions, but the profession recognition tool is made to find-right up Uk occupations only therefore really should not be applied additional for the perspective. Earlier in the day studies have understood British users playing with geotagged tweets and you may bounding packets , however, given that function of so it paper is to compare it classification together with other low-geotagging pages i made a decision to use date region given that a good proxy to have location. The new Myspace API brings a period zone profession for every single representative and also the pursuing the research is restricted to users associated with you to definitely of the two GMT zones in britain: Edinburgh (letter = twenty-eight,046) and you can 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.
