<p>If you’re looking closely, you will notice that I’ve added two elements to our previous ggplot. I’ve asked ggplot to fill in the columns with reference to the <code>dataset</code> column we’ve just created. Then I’ve also asked ggplot to alter the <code>position="dodge"</code> which places bars side by side rather than stacked on top of one another. You can give it a try without this instruction to see how this works. We will use stacked bars in a later chapter, so remember this feature.</p>
|
||||
<p>If you inspect our chart, you can see that we’re getting closer, but it’s not really that helpful to compare the totals. What we need to do is get percentages that can be compared side by side. This is easy to do using another <code>dplyr</code> feature <code>mutate</code>:</p>

<p>One element of R data analysis of census datasets that can get really interesting is working with multiple variables. Above we’ve looked at the breakdown of religious affiliation across the whole of England and Wales (Scotland operates an independent census), and by placing this data alongside a specific region, we’ve already made a basic entry into working with multiple variables but this can get much more interesting. Adding an additional quantitative variable (also known as bivariate data when you have <em>two</em> variables) into the mix, however can also generate a lot more information and we have to think about visualising it in different ways which can still communicate with visual clarity in spite of the additional visual noise which is inevitable with enhanced complexity. Let’s have a look at the way that religion in England and Wales breaks down by ethnicity.</p>

<p>For the UK, census data is made available for programmatic research like this via an organisation called NOMIS. Luckily for us, there is an R library you can use to access nomis directly which greatly simplifies the process of pulling data down from the platform. It’s worth noting that if you’re not in the UK, there are similar options for other countries. Nearly every R textbook I’ve ever seen works with USA census data, so you’ll find plenty of documentation available on the tools you can use for US Census data. Similarly for the EU, Canada, Austrailia etc.</p>
|
||||
<p>If you want to draw some data from the nomis platform yourself in R, have a look at the nomis script in our <a href="https://github.com/kidwellj/hacking_religion_cookbook/blob/main/nomis.R">companion cookbook repository</a>. For now, we’ll provide some data extracts for you to use.</p>
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
<p>Let’s start by loading in some of the enhanced tables from nomis with the 2021 religion / ethnicity tables:</p>

<p>I’m hoping that readers of this book will feel free to pause along the way and “hack” the code to explore questions of their own, perhaps in this case probing the NOMIS data for answers to their own questions. If I tidy things up too much, however, you’re likely to be surprised when you get to the real life data sets. So that you can use the code in this book in a reproducible way, I’ve started this exercise with what is a more or less raw dump from NOMIS. This means that the data is a bit messy and needs to be filtered down quite a bit so that it only includes the basic stuff that we’d like to examine for this particular question. The upside of this is that you can modify this code to draw in different columns etc.</p>

<p>The trouble with using grouped bars here, as you can see, is that there are quite sharp disparities which make it hard to compare in meaningful ways. We could use <a href="https://en.wikipedia.org/wiki/Logarithm#Probability_theory_and_statistics">logarithmic</a> rather than linear scaling as an option, but this is hard for many general public audiences to appreciate without guidance. One alternative quick fix is to extract data from “white” respondents which can then be placed in a separate chart with a different scale.</p>

<p>As you’ll notice, this is a bit better, but this still doesn’t quite render with as much visual clarity and communication as I’d like. For a better look, we can use a technique in R called “faceting” to create a series of small charts which can be viewed alongside one another. This is just intended to whet you appetite for facetted plots, so I won’t break down all the separate elements in great detail as there are other guides which will walk you through the full details of how to use this technique if you want to do a deep dive. For now, you’ll want to observe that we’ve augmented the <code>ggplot</code> with a new element called <code>facet_wrap</code> which takes the ethnicity data column as the basis for rendering separate charts.</p>

We’ve covered bifactorial analysis of the census data, compared this across years, and checked in each case to be sure that we’re representing the data accurately in the various visual elements of our charts. For the next chapter, we’re going to explore a wider range of ways to measure and represent religion.</p>

<p>In this chapter, we’ll explore the diverse variety of ways you can frame collecting data around religion. Before we dive into that all, however, you might be wondering, why does it all really matter? Can’t we just use the census data and assume that’s a reasonably accurate approximation? I’ll explore the importance of getting the framing right, or better yet, working with data that seeks to unpack religious belonging, identity, and beliefs (or unbelief) in a variety of ways, but an example might serve to explain why this is important.</p>
|
||||
<p>The 2016 presidential election result in the USA came as a surprise to many data analysts and pollsters. As the dust settled, a number of analysis scrambled to make sense of things and identify some hidden factor that might have tipped the balance away from the expected winner Hilary Clinton. One of the most widely circulated data points was the role of white evangelical Christians in supporting Trump. Exit polls reported that 81% of this constituency voted for Trump and many major media outlets reported this figure prominently, with public commentary from many religious leaders on the meaning this figure had the social direction of evangelical Christianity.</p>
|
||||
<p>Far too few observers paused to ask what those exit polls were measuring and a closer look at that information reveals some interesting nuances. There is only a single firm that runs exit polling in the USA, Edison Research, who is contracted to do this work by a consortium of major media news outlets (“the National Election Pool”), which represents ABC News, Associated Press, CBS News, CNN, Fox News, and NBC News. It’s not a process driven by slow, nuanced, scholarly researchers strapped for funding, it’s a rapid high-stakes data collection exercise meant to provide data which can feed into the election week news cycle. The poll doesn’t ask respondents simply if they are “evangelical” it uses a broader proxy question to do this: “Would you describe yourself as a born-again or evangelical Christian?” This term “born-again” can be a useful proxy, but it can also prove misleading. When asked if they are “born again” people who identify with a number of non-Christian religions, and people who might describe themselves as non-religious will also often answer “yes”. This is particularly salient given the 2016 exit survey asked this question before asking specifically what a person’s religion was, so as Pew Research reported, “everyone who takes the exit poll (including religious “nones” and adherents of non-Christian faiths) has the opportunity to identify as a born-again or evangelical Christian.”</p>

<p>This is quite a blunt measure, telling us how the whole average of all the responses compares in each case. But what is the relationship between these two measures for each individual? To find out more about this, we need to explore the correlation between points. We’ll talk about correlation analysis in a little bit, but I think it can be helpful to get ourselves back to thinking about our data as consisting of hundreds of tiny points all of which relate to a specific person who provided a range of responses.</p>

<p>This is pretty disappointing, as ggplot doesn’t know what to do with the x-axis as our points are 1-dimensional, e.g. they only have one value. But it’s easy to fix! You can ask R to add random numbers for the x-axis so that we can see more of the dots and they aren’t overlapping. This is called jitter:</p>

<p>You’ll also notice that we’ve hidden the x-axis value labels as these are just random numbers and not really something we want to draw attention to. We’ve also hidden the label for that axis.</p>
|
||||
<p>This is visually pretty chaotic, but you can see probably see some places where the dots are thicker and get the sense that there are more in the top than the bottom.</p>
|
||||
<p>Since this is quite a large plot, I’d recommend going one step further and making the dots a bit smaller, and a bit transparent (this is called “alpha” in R). The advantage of this is that we’ll be able to tell visually when dots are overlapping and register that there is a cluster. When they’re all the same black color, this is impossible to tell.</p>

<p>That’s a bit better. And we can start to see the weight of points hovering just over a value of 5, which aligns with our observation of the overall mean for this column of data a bit earlier in the exercise. But let’s say we’d like to be able to see this in an even more explicit way using a modification of the jitterplot with additional visual elements showing us where the mean is located. One example of this is called a boxplot:</p>
