<p>To split ages, the input for the <code>split_at</code> argument can be:</p><ul><li><p>A <ahref="https://rdrr.io/r/base/numeric.html"class="external-link">numeric</a> vector. A value of e.g. <code>c(10, 20)</code> will split <code>x</code> on 0-9, 10-19 and 20+. A value of only <code>50</code> will split <code>x</code> on 0-49 and 50+.
The default is to split on young children (0-11), youth (12-24), young adults (25-54), middle-aged adults (55-74) and elderly (75+).</p></li>
<li><p>A character:</p><ul><li><p><code>"children"</code> or <code>"kids"</code>, equivalent of: <code>c(0, 1, 2, 4, 6, 13, 18)</code>. This will split on 0, 1, 2-3, 4-5, 6-12, 13-17 and 18+.</p></li>
<li><p><code>"elderly"</code> or <code>"seniors"</code>, equivalent of: <code>c(65, 75, 85)</code>. This will split on 0-64, 65-74, 75-84, 85+.</p></li>
<li><p><code>"fives"</code>, equivalent of: <code>1:20 * 5</code>. This will split on 0-4, 5-9, ..., 95-99, 100+.</p></li>
<li><p><code>"tens"</code>, equivalent of: <code>1:10 * 10</code>. This will split on 0-9, 10-19, ..., 90-99, 100+.</p></li>
