And we also provide a wide range of support, we have training events like this one, we also have online materials and we have a help desk and offer other guidance, and I'll be talking more about that later. So, basically who can use it? Well, basically anyone. anywann can register with the UK data service. We are very commonly used by academic researchers and students and also by government analysts, by charities and foundations, etc. But you don't have to be using the UK data service for work and indeed anybody can register and most people can access to most of the data. Okay, so we are basically a large library or repository of data, so we don't provide the data ourselves in a sense we haven't gathered the data, we just provide access to it. So the data in fact come from a wide range of sources such as the official agencies like central government. A lot of the data is also from international government organisations or research institutions and individual academics from research grants. So if you were to collect some data as part of your research and particularly if it's funded by the ESRC you might want to make it available for reuse and you can deposit your data via us. Okay, so yes and when you want to get data you go to our website and this is the front page of the website and you can use the big search bar at the centre there to search for data that interests you or you can use the menu called get data and that's another way of browsing for data so you can search for key data, look at the list of the key data that we've got and you can also look at the main themes of data that we have about which I'll be talking in a bit. Okay, so what kinds of data do we hold? Well we have UK surveys and cross national surveys and these are large-scale government funded surveys. We've got longitudinal data which are similar to the other surveys except that these are ones that follow individuals over time. The international data are things like data from the United Nations for example the OECD and they are multinational aggregate data banks that you can download from the website. We have census data which the census data in the UK which is collected every 10 years and we have got the data from 1961 up to 2011 that are available and this comes as samples of the data as micro data so that could be used as in the same way that survey data could be used or we have aggregate census data so grouped data. We also have flow data and the boundary data for the census as well so you can combine say the aggregate and the boundary data in order to create maps of the census data. We've also got business data which is micro data about businesses and some administrative data and we also have a range of qualitative data sets so these are kind of multimedia things so they could be just text from interviews or other things so we also have mixed methods data. Okay then so what else can you get from the UK data service? Well we have a range of webinars, online workshops, conferences etc and if you look on our website you can see on the events pages everything that we've got there. We do a lot of guides, video tutorials, interactive data skills modules which can be useful for your own kind of personal learning if you just want to look at something, you want to look something up. We've got a guide to SPSS and a guide to STATR as well. We also run an email help desk so if you want to if you are trying to find some data and you're struggling to find something or if you've got hold of data but you're not quite sure about it you've looked at the documentation but you're thinking I'm not quite sure I understand this or you think there might be something wrong with it or anything along those lines we're happy to help and you just need to contact us for our help desk. The only thing the help desk doesn't do is to actually do the analyses of the data for you so we can't answer questions about analysis and we also from our website have a range of case studies about how other people have used the data. Okay and just a final point if you use any of our data then you must provide citation to the data and you'll find all the citation information alongside the in the catalogue pages for all the data. Okay then so what do we have in terms of crime data? Well as I mentioned before if you go to our website and you go to get data you can see data by theme so we have a range of different themes you can see a few here on the screen, ageing, crime, economics etc and the one that you're most likely to be interested in is the crime and data and what we have here is the list of key data sets so there are normally about four or five key data sets for each theme and they are for each of the different kinds of data so they're likely to be about five recommendations for surveys by recommendations for longitudinal data etc so that's a really good place to start if you've not used crime data before and you're just wondering what's available. We also have examples on how to find the data and we have case studies and teaching case studies as well in those pages. Okay then so what's actually in our crime data collection? So the data tend to be collected by research centres and large government organisations and in terms of survey data it's anonymised survey data and it's generally at the individual level and these data are indeed very heavily used by a wide range of users including academics, government organisations etc and some of them are used to obtain the official statistics used by the government so the crime survey for England and Wales and the Scottish Crime and Justice Survey are examples of those. So the crime survey for England and Wales was run for many years as the British Crime Survey despite covering only England and Wales in many of the years and this has been run since 1982 and it became an annual survey ever since 2001 to 2002 and the kinds of topics that it covers are basically experiences of crime and it's used to estimate the levels of crime in the UK sorry in England and Wales. There's also the Scottish Crime and Justice Survey and this has very similar topics so you can see the topics that are covered in this so things about experiences of being a victim of crime which could include violent crime or property crime all sorts of different things. The public perception of crime, the police and the justice system and they also have a self-completion questionnaire and this is true also of the crime survey for England and Wales which covers the kind of sensitive topics that people might not want to talk about if they were actually directly in front of an interviewer so things like drug abuse, partner abuse, sexual victimisation and stalking. Obviously it doesn't cover everything so crimes without a specific victim or against businesses or crimes without a victim to interview obviously are not covered by these sorts of survey data. Okay so here's the list of some of the key survey data on crime that are available from the data service so I've mentioned the first two there's also a commercial victimisation survey and amongst data sets that have not been run recently there's an arrestee survey and conflicts and violence in prison survey but unfortunately they're not recent. The longitudinal data includes the Edinburgh sorry study of youth transitions and crime et cetera. Okay then so how do you get hold of these data? Well there are four levels of access most census and international data are available by open access and we have a small number of survey teaching data sets that you can get so these are data sets that you can just go to the website and you can just download and you don't need to be registered with the data service to get them. The next level the end user license data sets this covers the vast majority of what we have on our website essentially so the vast majority of survey data sets will be available under the end user license and agreeing in effect with the end user license not to share the data with anyone else or to try to identify any individuals which would in fact be very hard anyway with these kinds of data and in order to do that you would need to get access to that you would need to register with the data service and you would if you're based at a UK higher education institute you would use your username and password to log in via the UK data service. If you don't have one of those then that's fine we'll be able to send you login details that you can use. Okay there are two other kinds of access that's worth knowing about so special license data these are data that has slightly more detail in them and they are slightly more potentially disclosive therefore which is why it's slightly harder to get hold of and what you'd need to do is to apply for access to those data and there may be a bit of a delay on getting that a matter of a month or so or two and when you've been given permission to get the data you'll be given a passphrase and then you just download that from the UK data service website using the passphrase to access it. Secure access data is also known as controlled data and these data are even more potentially disclosive and again there's a procedure to get hold of these data and you'd access them via SecureLab which is an online environment. Okay then so a couple of key things documentation is available for all of the surveys so here's the documentation for the commercial victimisation survey 2017 you'll see that the documentation does vary depending on the particular dataset but you'll see in general this kind of thing something like questionnaire technical reports and all of that is available to look at without any kind of registration. Okay so you have a few options in terms of analysing these data if the data is in our online tool called Nestar then you'll be able to analyse it using that and it should be obvious because it'll say one option for accessing it will be to explore it online and this is just a screenshot from Nestar and essentially what it is is it allows you to look at the variables so you can see the coding for the variables and it often has information about what the exact question was for example so you can explore the data without having to download it and use the statistics package so it's particularly good for teaching purposes really and you can also do simple analyses such as produce frequency tables you can wait and you can do cross tabs and basic regressions and things like that with it so the other way of approaching it which is the one that most people would use for using more full analyses would be to directly use it on the computer so you download the data assuming it's one that you can download and you would analyse it using a statistics package like SPSS data or SAS or in this instance R or R studio okay and I think that was everything I wanted to say so does anyone have any questions about the data service or what we've got available?
