<p>Hello</p>
<p>I've noticed that employment status of some variables in the Main survey don't match. For instance, EMPLOY, JBFT_DV and JBSTAT. That is, a person unemployed according to EMPLOY appears "in paid employment (full or part-time)" in JBSTAT. Is it due to a timing issue, or am I missing something?</p>

<p>Dear Understanding Society Team,</p>
<p>I am looking at change in health status if individuals accross wave 2 to wave 5. My variable of interest comes from the longitudinal self-completion questionaire therefore I believe the right weight to use for my fixed-effect models is indscus_lw. However, when I want to run my fixed effect model with this pweight, stata tells me that the weight must be constant within pidp. To which values should I therefore set my weight to? What does a indscus_lw=0 mean?</p>
<p>Thank you for your help,</p>

<p>Hello,</p>
<p>I am using the Harmonised BHP and Understanding Society dataset to evaluate the impact of raising the minimum legal age for purchase of e-cigarettes on smoking prevalence using regression discontinuity design. I have aggregated the US wave 2-7 datasets into one and reshaped them, however I am not able to merge it with the cross wave id dataset, which contains information on individual's month and year of birth. Without this information, I cannot carry out the analysis. If you could please help me I would really appreciate it! Thank you.</p>
<p>Please find below the description of what I did:</p>
<p>1. I merged waves 2-7 from responding adults 16+ dataset ("indresp") and reshaped it into long format<br />2. I merged waves 2-7 from youths (age 10-15) dataset and reshaped it into long format<br />3. I appended the 2 datasets together <br />4. I tried merging the cross wave id dataset ("xwaveid") with the combined long file as follows:</p>
<p>merge 1:1 pidp using "/Users/.../xwaveid.dta"</p>
<p>however that did not work out because pidp did not uniquely define observations in the long format. I then reshaped the combined file into wide format and repeated the above command to obtain 80'290 matches instead of the full 121'665 that are in xwaveid file. Could you please let me know what am I doing wrong and how can I assign the month and year of birth to all individuals from both youth and adult questionnaires?</p>
<p>Additionally, if my data is in long format, can I run regression discontinuity analysis as if I had cross-sectional data?</p>
<p>Thank you in advance. I look forward to your answer.</p>
<p>Kind regards,</p>

<p>We are doing some research on the effect of interviewers on the effectiveness of incentives, one of the data sets we are using is the Innovation Panel (Wave 1). It is the sample file which shows the fieldwork outcome for each issued address and has the interviewer ID attached. We have come across a potential problem with your analysis which relates to whether the outcome data is based on the initial (prior to re-issues) or final (after re-issues) outcomes. We think it is the initial outcome but cannot tell from the information provided. Because our analysis uses the experimental design of within-interviewer allocation of the incentive, it is important that our analysis is based on the initial rather than the final outcomes.</p>
<p>I wonder whether a data set with the initial outcome codes is available for Innovation Panel wave 1 and how we can obtain it?</p>

<p>I am working with the Wave 6 Indresp file using Stata. I have limited the sample to respondents who have a paid job regardless of whether they are employees or self-employed as well as by an adult main cross-sectional weight greater than 0 using the following code:</p>
<p>keep if (f_jbhas 1 | f_jboff 1) & (f_jbsemp 1 | f_jbsemp 2) & f_indinub_xw > 0</p>
<p>From the tabulation of the variable f_jbrise (pay includes annual increments), 3,073 respondents were not eligible for this question and this can be assumed to be due to that they were self-employed and NOT employees as f_jbrise only applied to employees. However the frequency for the self-employed in the sample is 2,584 which leaves 489 respondents who were not eligible unidentified. This is confirmed by a cross-tabulation of f_jbrise and f_jbsemp (employed or self-employed in current job). I have tried to identify these 489 respondents by cross-tabulating possible variables that might include this group without much luck. However a cross-tabulation of f_jbstat (current economic activity) and f_jbsemp for these 489 gave some contradictory results:<br />1) 468 of the 489 respondents in paid employment were employees but were classified as not eligible for the f_jbrise question. Others (3 retired, 1 maternity leave, and 12 full-time students) were also employees. <br />2) There is an overlap of mutually exclusive categories (5 self-employed respondents are also employees).</p>
<p>Can you help me understand who these respondents are, why they were classified as not eligible for the f_jbrise question and how they should be treated in an analysis? I have attached a word document with some notes and some tables of the outputs.</p> Understanding Society User Support - Support #985 (Resolved): Weights for pooled cross-section ov...https://iserredex.essex.ac.uk/support/issues/9852018-06-22T10:51:51ZNhat An Trinh
<p>Hello,</p>
<p>Although this issue has already been discussed a couple of times, I would like to address the selection and use of the appropriate weights when pooling across all waves of Understanding Society once again to avoid any mistakes. I'm very much appreciating the guidance that has been provided so far, but haven't found a clear answer to my question and thus be extremely grateful if someone could help me out.</p>
<p>For my analysis of intergenerational social mobility across labour market entry cohorts, I am using all waves including all samples of Understanding Society in a pooled cross-section. Obviously, I have dropped all duplicates as I want to have each observation only once in my dataset and take the first interview in which the individual has indicated both her first occupation and year of leaving school/further education as my observation of interest. In line with [<a class="issue tracker-3 status-5 priority-4 priority-default closed" title="Support: weights for pooled cross-sections over waves (a)-(f) (Closed)" href="https://iserredex.essex.ac.uk/support/issues/758">#758</a>], I have constructed the individual cross-sectional weight as follows:</p>
<p>gen xweight = .</p>
<p>replace xweight = a_indpxus_xw if wave == 1<br />foreach x in b c d e {<br /> replace xweight = `x'_indpxub_xw if inlist(wave,2,3,4,5) <br />}<br />repalce xweight = f_indpxui_xw if wave 6<br />replace xweight = g_indpxui_xw if wave 7</p>
<p>Is this the correct way of selecting the cross-sectional weights? And do I need to do anything else such as rescaling to correctly apply them for my pooled cross-sectional analysis (i.e. calculating social mobility rates and proportions of class of origin and destination by labour market entry cohorts)?</p>
<p>Thank you very much!</p>

<p>Hi Stephanie</p>
<p>I have merged individual level data on the BHPS across waves and am having difficulty merging with the house price data set.</p>
<p>The rule is that am i am suppose to find a unique macro identifier for the two data sets in which am using "region" as you advised duringUndSoce training but the problem is that it still doesn't merge.</p>
<p>It is suppose to work using merge 1: m region using longfile.dta</p>
<p>But it keeps saying the variable does not uniquely identify observations in both data sets. i also converted "region" from string to numeric</p>
<p>Please would really appreciate your help.<br />Apparently the merged data set which you helped me with during the training 2 weeks ago does not work with my Stata version 13.0</p>
<p>Will be so grateful for your kind help.</p> Understanding Society User Support - Support #966 (Resolved): Active Healthy Kids Wales - Call fo...https://iserredex.essex.ac.uk/support/issues/9662018-04-24T15:41:53ZRichard TylerR.P.O.Tyler.837039@swansea.ac.uk
<p>Dear Understanding Society members,</p>
<p>I am contacting you on behalf of the Active Healthy Kids Wales report card expert group <a class="external" href="http://www.activehealthykidswales.com/">http://www.activehealthykidswales.com/</a>.</p>
<p>As the AHK-Wales expert group of academics, educators and allied professionals we are concerned about the health of children in Wales. The AHK-Wales expert group aims to use data on physical activity/inactivity behaviours and influences to advocate for children’s right to play, to be hooked on sport and dance, learn and achieve, and be active and healthy. We are motivated to promote healthy active behaviour and physical literacy in children. Our mission is to produce AHK-Wales Report Cards that provide a clear evidence base on quality indicators related to physical activity that should be used to advocate and influence local, regional and national policies and investments in physical activity for children and young people.</p>
<p>We are currently in the process of assigning grades to the following indicators:<br /><strong><ins>Physical Activity and health behaviours and their outcomes</ins></strong><br />- Sedentary Behaviour<br />- Physical Activity<br />- Active Transport<br />- Organised Sport Participation<br />- Physical Literacy<br />- Physical Fitness</p>
<p><ins><strong>Settings and Influences on Physical Activity and Health</strong></ins><br />- Family and Peer Influence<br />- School<br />- Community and the Built Environment<br />- National Policies and Strategies</p>
<p>I can see that on your website, all data is reported for UK children on the whole, but I am wondering whether you have data specific to children/adults in Wales? Further, if so, is there any way that we could have access to the Welsh data?</p>
<p>Yours sincerely,<br />Richard</p>

<p>I'm in a very urgent/immediate situation so if you could direct me or find me a dataset (or tell me how to find it) that looks at (young) people use of social media and its impact on mental health that would be very appreciated, it's for a project where I have to use the R software to compute statistics and show that my analysis helps (or not) to extent knowledge on the research problem (in my case the correlation between the use of social media and mental health).</p>
<p>my tutor suggested I came through your institution and after spending 2 days in your website I have given up, there is so much stuff. my tutor tells me first:</p>
<p>'Did you find any information on the variables you need through US?'</p>
<p>I had no clue what he meant, I guessed I would be interested in variables such as age? nationality? gender? ethnicity or as many variables as I want, based on my specific interest.</p>
<p>His reply was:</p>
<p>'The understanding society dataset is huge so in the first instance you would need to identify where the bits you need are. Look for a “code book” or other guide to the variables. You’re looking specifically for variable names and for the file name containing them. I can help with fiddly aspects of loading this into R but you need to go through the administrative side of getting to grips with what’s in the dataset'</p>
<p>I went as far as finding this page, then I get lost, when I click on some of the links I get e.g. 'variable 160'...what does it mean? that that study has 160 variables and I have to know what to unpick based on my want/need?</p>
<p>sorry if I'm asking silly questions but I have been chucked into a stats course and hve little knowledge and understanding. can you help? many thanks in advance. danilo</p>
