ageing global population and the fastest growing group being those 80years and above
(UN 2017 Revision), future anthropometric studies for clothing will need to address
these intergenerational clothing requirements. For example, SizeUK had an upper age
group of 75 plus (eldest person was 93years), but future studies will need to include
data for centenarians if they are to meet an inclusive design and sustainable strategy
for RTW clothing, that is, to provide a choice of garment shape, size, and fit for all
members of a population that meets the required sustainable process.
There are several options for subject recruitment, but if software is designed to con-
stantly monitor registration, subjects can be selected in two stages: first, to meet the
recruitment strategy (gender, age, and geodemographics), and, second, to ensure other
national statistics (ethnicity and socioeconomic grouping) before being invited to a
center to be scanned.

3.4.2.7 Model data collection center

A model venue for the collection of data, setting out the orientation of equipment for
easy team measurement operations and subject processing, needs to be arranged and
tested before any necessary training. A data collection center, whether a static venue
or a mobile unit, is likely to comprise

l a reception desk with a PC;
l additional registration facilities;
l an auto height gauge;
l an auto weight scale (e.g., a body composition monitor);
l a set of traditional anthropometric tools;
l a foot, hand, and/or head scanner;
l a whole-body scanner, with dedicated PC and integral changing space;
l storage facilities (e.g., underwear/scan wear, cleaning equipment, and materials).

3.4.2.8 Proofing survey

Crucial to the efficient operation of a survey and to its overall cost is the number of
subjects that can be processed per day in a given data collection center or unit. Issues
that could arise to affect the operation of a collection center might include the selected
equipment, the data collection team, subject ages, the location of the data collection
center, and the recruitment of a steady stream of subjects for measurement. To test the
process of the layout and efficiency of the equipment and to provide an estimate of the
daily subject throughput, it is important to conduct a proofing survey of at least 40 sub-
jects (ISO 20685). Subject recruitment needs to be in accordance with the objectives
of the study and in the proportions indicated in current national census for gender, age,
and ethnicity.
If a survey is not to be conducted using a mobile unit (Fig. 3.4), then the identifi-
cation and inspection of all venues in selected cities would ideally be completed
before the selection and/or training of a team or teams.
