Standardising the process for collecting demographic data in administrative data collections can be difficult if data collection is part of the routine activity of an organisation and that activity itself varies in context between different operational centres.
The limitation of this study is that it is based on the analysis of secondary data, with data collected in a large number of cancer treatment centres, making it difficult to standardise data collection.

The most difficult component of data collection was securing an interview with the general practitioner due to time pressures on their work.
A deeper understanding of this observed association will demand future studies that do a better job establishing the temporality of the most relevant events (deployment, mental disorder onset, and IPV); this will be difficult without longitudinal data collection.
The census uses imaging drones and automated image recognition techniques to collect data that otherwise would have been too expensive or too difficult to collect using traditional data collection techniques.
Although mobility makes data collection difficult, it also renders the pastoral economy viable.
Assessing the degree of involvement and participation in thoracic surgical research as well as surgical quality improvement conducted across Canadian institutions is difficult as no common data collection system and no prior studies exist.
River gauging stations are declining globally and although historical and current gauges are providing useful and frequent data in the developed world, the number of gauges in developing and emerging economies is very small and measurement stations are often very far apart and in remote locations thus making inference of processes and data collection difficult.
Large numbers of poisonings and deaths occurred, but the emergency circumstances during a famine made data collection difficult, with limited opportunities to record the extent of the exposures.
Similarly, describing the injuries incurred is difficult due to varying data collection methods and a lack of a commonly used tool to provide appropriate information about the injuries.
