Socio-economic status of current participants
Some participants did not fill in their postcode, resulting in the
total
number
of
postcodes
received
from
LGPS
participants
being
59, and 179 from BTO participants. Scottish and Welsh postcode
scores were not used in this analysis due to the small sample size
from
these
countries.
Mean
and
median
postcode
scores
for
both
the Leeds Garden Pond Survey (LGPS) and BTO Garden BirdWatch
(GBW) schemes fell below the 95% confidence intervals calcu-
lated from resampled national datasets (Leeds and all England data
respectively)
(Table
6).
As
higher
IMD
scores
represent
relatively
more deprived areas than lower scores, this indicates that partic-
ipants of these schemes live in postcode areas that are relatively
less
deprived
than
the
local
and
national
dataset
as
a
whole
(Fig.
2).
