Redmine Support #874 (Closed): try to link the birthweight to each childhttps://iserredex.essex.ac.uk/support/issues/8742017-11-02T15:30:22ZYIN XUyin.xu@kcl.ac.uk
<p>There is a file called a_natchild containing the information about the natural children including birth weight, gestational age, and breastfed. <br />There is another file called a_child containing information about child's identifier(pidp), childs age (a_dvage). <br />I had a hard time trying to link those two files together. a_natchild only provided a_childno, which is the birth order. But I don't know which kid that's apply for (e.g. pidp). Is the a_childno from a_natchild same as the a_childpno ? Do you have any suggestions about how to link the birthweight to each child?

<p>On your data linkage page (<a class="external" href="https://www.understandingsociety.ac.uk/about/data-linkage">https://www.understandingsociety.ac.uk/about/data-linkage</a>) it states that consent for linkage was asked in Waves 1 and 5.

<p>Could you let me know when this data is planned to be made available? We are looking to include this information in a grant proposal and the submission date is the end of September.</p>

<p>In the user guide for the BHPS' TTWA identifiers it says "Travel-to-work areas are as defined in 1998 and are based on those electoral ward boundaries existing on 21 April 1991 (Census day)", and the range of codes is described as 3-digit numerical.</p>
<p>However, in the actual data, 9-digit alphanumerical codes are used.</p>
<p>Please confirm which TTWA coding is used in the data. (Are these the 2001 TTWAs maybe?)</p> Support #750 (Closed): Industry codeshttps://iserredex.essex.ac.uk/support/issues/7502017-03-17T10:02:08ZAina Gallego
<p>Are there cross-walk that map the 1980 and 1992 industry classifications used in the BHPS?</p>
<p>I need to create a variable about the industry in which respondents work that is consistent for the 18 waves of the BHPS. The information is contained in two main variables: jbsic, which uses the UK SIC 1980 classification and is available until 2001 and jbsic92 which uses the UK SIC 1992 classification and is available from 2001 onwards. I would need a cross-walk to map each category of one of the variables to the closest category in the other variable.</p>
<p>I'm sure many users have had similar problems. I would be grateful if you could indicate how to do this.</p>

<p>Hi,</p>
<p>I'm working on a project that examines changes in individual incomes over different periods of years.</p>
<p>I'm aware you produced a note titled "Pooling data from different waves of Understanding Society for cross-sectional analysis", which describes how to construct yearly cross-sectional weights from pooled waves. How would you recommend constructing longitudinal yearly weights that would be appropriate for analysing samples defined as "all individuals observed in year X and year Y" (where X and Y are not necessarily consecutive)?</p>

<p>To whom it may concern</p>
<p>I am a researcher broadly interested in environmental behaviour survey instruments and I have been having a look at the Environmental Behaviour module in wave 4 of the Understanding Society UK household longitudinal study.</p>
<p>I wanted to understand the source of your questions in this module.</p>
<p>I note helpfully you provide the sources, but I was having difficulty tracking down what “DEFRA adapted” may be.</p>
<p>I believe “UKHLS” and “BHPS” to correspond to the Understanding Society and British Household Panel Survey respectively.</p>
<p>I thought that “DEFRA adapted” might have referred to the consumer segmentation exercise DEFRA completed in 2008, but I was unsure about this.</p>
<p>Any help you can offer would be most welcome.</p>

<p>Hello,</p>
<p>In the file a_natchild the variable a_childno records every child listed by a given adult. However, some of those children listed by the same adult share the same identifier code (a_lchno). That is, there are repeated children identifier codes for a given adult (repeated observations with identifers a_hidp a_pno a_lchno). Is there something am I missing or is it an error?<br />This is something that occurs too in the file a_adopt.</p>
<p>Thank you very much in advance.</p>

<p>We are researching changes in household income over time, and are interested in determining which components (labour earnings, benefit income, etc.) are associated with the observed changes.<br />As far as I can see, the "hhresp" dataset contains an aggregate income variable but no income components. I was wondering if there are plans for those to be released?</p>
<p>In the meantime, I was considering using the information available in the "indresp" dataset, there are however some issues that I was hoping you could help me with.</p>
<p>a) w_hhnetinc1 is different from the sum of w_netinc1 for all individuals in the household. I understand this is due to the fact that w_hhnetinc1 includes additional information on proxy and individuals who did not respond to the individual questionnaire. Is that correct? Are there other possible sources of difference?</p>
<p>b) I also computed the sum of the individual income components for the first wave as follows:<br />egen a_totalinc = rowtotal(a_inc1lab a_inc2misc a_inc3prben a_inc5inv a_inc6pen a_inc7sben)</p>
<p>and compared it with a_netinc1. For 46794 cases the variables take the same value, but not for the other 4200 cases. I was wondering whether I am missing some income component? Or is there perhaps imputed income included in w_netinc1 but not in the component variables?</p>

<p>Hi there,</p>
<p>I am using Wave C in my dissertation and I've read that because Understanding Society's Dataset is so complex, I need to use svy commands on stata to account for this. However, when I do this, I get no standard errors, t values, p values, or confidence intervals. I have used the following command:</p>
<p>svyset c_psu [pweight=c_indscub_xw], strata(c_strata)</p>
<p>and then I put svy: reg y x1 x2 <br />However, it doesn't work and I am not sure why. <br />Note: 87 strata omitted because they contain no population members.<br />Note: Missing standard errors because of stratum with single sampling unit.</p>
<p>Does the above mean I need to do this:<br />svyset c_psu [pweight=c_indscub_xw], strata(c_strata) singleunit(scaled)<br />then drop alll 87 strata that have been omitted and then do my regressions by putting svy: first??</p>
<p>Thanks in advance,</p>

<p>Hi,</p>
<p>I'd like to create variables for a total number of biological children for individuals in each wave. My understanding is that nnatch gives me the number of biological children currently residing in the household, and lnprnt is for the number of children outside hh in wave 1 and only applies to new entrants in later waves. What I want is a series of variables for the total number of children in each wave (no matter dead or alive, residing in the hh or living separately), i.e. something along these lines:</p>
<p>pidp a_nch b_nch c_nch d_nch e_nch<br />1 0 0 0 1 1 (a person has a new child between waves 3 and 4)<br />2 1 1 1 1 1 (a person enters the study with one child and doesn't have any more children)</p>
<p>Next I'd like to do the same for the total number of adoptive children.</p>
<p>Any advice on this would be much appreciated.</p>

<p>Would it be possible for you to tell me what component variables make up the derived variable in the subject heading? In particular, I am looking for a measure of gross labour income at household level (and at an individual level if possible).

<p>I need to estimate weighted medians for the BHPS sub-sample in UKHLS wave 3. What are the most appropriate weights to use for this?</p>
<p>Is it valid to use c_hhdenub_xw and c_indpxub_xw, even if I am restricting my analysis to just the BHPS sub-sample?</p>
<p>If not, then what would you advise I should do?</p>
