Year

Year of survey.

Changes between years

Statistical significance is measured at the 5% significance level ( p value < .05).

Statistically significant differences between survey years ( p < .05) are indicated by the symbols and (significant increase or decrease respectively).

The symbol ≈ indicates there is no statistically significant difference between survey years.

A statistically significant difference is likely to represent a real change over time, rather than random variation due to the sampling process.
