The UK Statistics Authority standards state plain English should be used:
Include an impartial narrative in plain English that draws out the main messages from the statistics
Avoid: Language that needs to be “translated” by journalists or commentators into simpler English.
Plain English is clear language, with no jargon, that is understood by all readers. This isn’t “dumbing down” information, but opening up statistics and statistical commentary to everyone. Users don’t stop understanding text because it’s written clearly, but they stop understanding when it is complex.
Don’t use formal or long words when easy or short ones will do. You can generally avoid this by breaking down what you are actually doing. Where technical terms can’t be avoided, they should be explained in the text, not just in a footnote.
To write in plain English, think about the following:
Who’s your audience?
Unless you know otherwise, think of your audience as people who take an interest in your subject but have no detailed knowledge. Use your writing to guide readers through the subject and help them identify what is most important.
What are you going to say?
Think about what your readers want to know. You do not need to tell them everything. Use your opening paragraphs to:
- summarise succinctly what you’re writing about
- tell readers what information they’ll find
- put your research into context.
