Counting the Past

Censuses, price series, parish registers and shipping lists let you ask questions no diary can answer, such as how many and how much. They also carry the assumptions of the clerks who filled them in.

What a learner can do afterwards

  • Convert a historical wage or price into today's terms and state what the conversion assumes
  • Name two questions a serial record can answer that a single document cannot
  • Identify one systematic bias in a historical record, such as who was left off a census and why

1 · Read

Lists from the past answer how many and how much. Parish books, tax rolls, ship logs, and census sheets used one form year on year. Sums and drifts across years show what no lone letter proves.

Try it together

To set an 1850 wage beside one today, pick a wage, find the price mark of both years, and split. Then own the catch: baskets of goods differ, so the fit stays rough.

Each list mirrors its clerk. A parish logged christenings, not births, so unchristened babes slip past. A noon mart poll misses night hands, and a tax roll skips the poor. Name the lost group before you quote the count.

Good to know

Two lines can climb as one with no tie between them. Bread cost and thefts may both track one lean harvest. Check order, seek a path, and test some third driver before you claim a cause.

Long lists show drifts no diary can, but each count hides its clerk, its gaps, and its baskets, so test ties before you trust them.
