<p>After reading the third point (collecting data) on <a href="https://stats.stackexchange.com/help/on-topic">this list</a>, I asked <a href="https://stats.stackexchange.com/questions/147625/what-is-the-best-method-for-collecting-up-to-date-information-regarding-world-wi">this question</a> (What is the best way of collecting birth rate data?).</p>

<p>My question is: why is "collecting data" listed as on topic, however, when this question about collecting data is posed, it's put on hold as off-topic?</p>
