Census 2021 was undertaken during the coronavirus (COVID-19) pandemic. This may have influenced how people perceived their health status and activity limitations, and therefore may have affected how people chose to respond.

Religion in Caerphilly
In 2021, 56.7% of Caerphilly residents reported having "No religion", making it the most common response in this local authority area (up from 40.9% in 2011). Because the census question about religious affiliation is voluntary and has varying response rates, caution is needed when comparing figures between different areas or between censuses.
Across Wales, the percentage of residents who described themselves as having "No religion" increased from 32.1% to 46.5%.
In 2021, 36.4% of people in Caerphilly described themselves as Christian (down from 50.7%), while 5.7% did not state their religion (down from 7.5% the decade before).
There are many factors that can cause changes to the religious profile of an area, such as a changing age structure or residents relocating for work or education. Changes may also be caused by differences in the way individuals chose to self-identify between censuses. Religious affiliation is the religion with which someone connects or identifies, rather than their beliefs or religious practice.

Census 2021 was conducted during the coronavirus (COVID-19) pandemic. This may have influenced how people perceived and rated their health, and therefore may have affected how people chose to respond.

About the data
Census data are adjusted to reflect estimated non-response so that the published results relate to the entire usually resident population as it was on Census Day (21 March 2021).
Those respondents who were on furlough because of the coronavirus (COVID-19) pandemic were asked to classify themselves as "temporarily away from work" to ensure they remained in the economically active population.
Students are counted as usually resident at their term-time address even if they were not physically present there on Census Day.
The questions relating to disability differed slightly between 2011 and 2021 to ensure that data were more closely aligned with the definition of disability in the Equality Act (2010). There was also a change to question wording for unpaid care, for more information read the health, disability and unpaid care quality information.
Age-standardised proportions are used throughout the health, disability and unpaid care sections. They allow for fairer comparisons between populations over time and across geographies, as they account for differences in the population size and age structure. The 2013 European Standard Population is used to standardise proportions.
Percentages and percentage point changes have been individually rounded to one decimal place. This means they may not sum exactly.
