Agriculture, forestry and fishing is 5.9% of employee jobs in Carmarthenshire, against 1.4% across Great Britain (9,000 jobs in 2015, 4,500 in 2024). Where one industry carries that much of a local economy, rents and prices tend to move with it.

62% of the energy performance certificates lodged across Ammanford's postcode districts are below band C (10,091 certificates). Clarity measures areas rather than individual homes, so this is the share of the local stock likely to need energy-efficiency work before it meets a band C standard, not a survey of any one property.
The five-year forecast quoted above (Savills, Wales) is a regional figure for Wales as a whole, not a forecast for Carmarthenshire, and Clarity does not rank on it.
