Current month, in context.
The aggregate JSON is monthly data, so this module compares the current provisional month with complete monthly aggregates only.
No historical fill curve is inferred here: this aggregate feed does not contain day-level fill history.
Read this as starts, not completions.
Commencement notices are notified intent to start works, generally lodged 14-28 days ahead of commencement. They are not completions and they are not a measure of homes delivered.
