Every report can go back in time. Change the date range and the whole page, every signal, rate, map, and briefing, is worked out again for that past month.
How to use it
On the report, use the Date range picker near the top and pick any complete past month. The whole page, not just the headline, is redone for that month. The full report and the PDF work the same way, so a downloaded report always shows the month you picked.
Why the newest month looks low
The newest month is provisional: its numbers can still rise as late HPD records arrive. Step back one month and you are usually looking at more complete figures. Read a fresh month as "so far," not "final." See Why did the number change.
Reading a trend over time
Each signal also shows its own trend line across months. The month a signal's record begins is marked, so its first month is never mistaken for a sudden jump in activity.
