Older members of population, particularly fecund ones, in pairs,

Primary sources of information are great because they are first hand information from someone who was there. Secondary sources are based on primary sources, and may be biased.
An inherent problem in using secondary sources of data is that the data may have been skewed or manipulated a bit. Primary sources of data are always more reliable than secondary sources.
The source is the main thing that makes data unreliable. For example: I asked Dave and Jack to get me the population of a town; Dave gets 300,000 and Jack gets 251,000. They both went to different sources and got different results.
