secondary sources of data - official statistics Flashcards
What is an official statistics?
Quantitative data gathered by the government or other official bodies - can be found on website of the Office for National Statistics.
Examples of official statistics
( census / births / deaths / marriages / crime / suicide/ unemployment)
- Govt. collect data to use in policy making
- Charaties / trade unions / businesses and churches also collect statistics
What are the two ways of collecting official statistics?
1) Registration - e.g law requires parents to register births
2) Official surveys - e.g census
Practical advantages
- Free source to a significant amount of data → only state can afford to do such wide scale research e.g the Census / only state can compel ppl to do it
- Allow comparisons between groups → e.g compare education between gender
- Can show trends and patterns over time ( as collected at regular intervals) → able to gather causal relationships
Practical disadvantages
- Govt collects data for own purpose - may be no statistics for sociologist interested in
E.g Durkheims suicide study had no statistics specifically on religion of suicide victims - Definitions state uses to collect data different from those sociologists would use → may create different views e.g poverty
- If definitions change overtime → hard to make comparisons
Definition of unemployment changed between 1980 - 1990s so not comparing like with like
theoretical
representativeness + / -
+ As a large sample is covered → more representative → able to make generalisations and test hypothesis
More people covered than an individual sociologist would be able to access
- Statistics gathered from official surveys - British crime survey / general household survey → may base on a sample of the relevant population
theoretical
Reliability
++ Collects data in a standardised way by trained staff / following set procedures → reliable as those trained will allocate a given case to the same category
- -Not always wholly reliable → census coders make errors or omit information when recording data from census
- -Public may fill in the form incorrectly
theoretical
Validity
++ Hard statistics - do succeed in doing this → marriage / death statistics do give an accurate picture
– Soft statistics - give a less valid picture → e.g police statistics do not record all crimed
– British crime survey 2011 found only 38% of crimes from the survey were reported to police
positivism view
- Valuable resource for sociologists
- Statistics are true and objective measures of real rate of crime … etc
- Develop hypotheses to discover causes of behaviour patterns statistics reveal - science
- Use official statistics to test hypotheses
Durkheim used official suicide statistics able to show protestants had a higher suicide rate than catholics
Interpretivism
- Lack validity
- Do not represent real things or social facts
- Merely represent labels that some give to the behaviour
E.G in suicide rates only tell us what coroners deem to be ‘suicide’
Should rather investigate how they are socially constructive
