Redmine Understanding Society User Support - Support #1733 (Resolved): Covid Survey - Measuring Internal ...https://iserredex.essex.ac.uk/support/issues/17332022-07-25T13:52:23ZMorgan Ward
<p>Hello,</p>
<p>I am attempting to measure 3-monthly internal migration moves between UK regions during the Covid pandemic, using your Covid survey data.</p>
<p>To do this, I have created a variable to identify where movements have taken place between waves, e.g., for moves between May - July 2020:<br />gen regi_moves = 1 if cd_gor_dv != cb_gor_dv</p>
<p>However, when I longitudinally weight these regional moves using betaindin_lw, the unweighted counts of moves are significantly reduced. E.g., the unweighted count of 147 moves into the South East between May - July 2020, is reduced to a weighted count of 3.324 moves.</p>
<p>Is there a way of producing valid weights for the analysis of moves between Waves please, which do not have such reduced counts? I was hoping to compare sequential Waves, excluding Waves 1 and 3. So comparing Waves 2 - 4, 4 - 5, 5 - 6 etc. The reduction in counts prevents me from generalizing rates of internal migration moves with any accuracy.</p>
<p>Any help will be greatly appreciated.</p>

<p>Hello,</p>
<p>I am attempting to ascertain how many people moved into each U.K. region per year. To begin this process, I have run a svy tab of the mvyr and gor_dv variables, weighted with svyset k_psu [pweight = k_indpxui_lw], strata(k_strata).</p>
<p>However, the counts do not change between the weighted and unweighted data, and therefore my crosstabs returns typically single-digit counts of moves where thousands are expected in relation to the true population size.</p>
<p>I was hoping that you could inform me if/how weights could be used to make these counts of movements representative of their true population size?</p>
<p>I hope this is clear - apologies if I have missed something simple! Thank you</p>
