How old the living Jacobas are
born that year still alive today
Of the 296 babies given the name since 1900, about 140 are alive — 49 in every hundred. The dotted line is the median: half were born before 1985 and half after.
An estimate, not a count. SSA births aged forward through SSA cohort life tables, which know nothing about who left the country or arrived in it — so for a name that mostly came to America rather than being born in it, this is a floor rather than a figure. Where you fall among living Americans.

Jacoba among the living
How many people each country's register counts under the name, rather than how many were given it in any one year. Each register was read on one date, and they are not the same date.
| Country | Spelling | First forename | Any forename |
|---|---|---|---|
| the Netherlands girls | Jacoba | 40,396 | 124,753 |
| the Netherlands boys | Jacoba | 5 | 867 |
| Finland girls | Jacoba | — | 10 |
A count of people on a register – the Netherlands on 1 January 2018, Finland on 4 August 2026 – and not of births, so it cannot be compared with the figures above. Names with very few bearers are withheld, and a dash in the first-forename column means the register would not say rather than that nobody goes by it.
Where Jacoba lives in Spain
Not a count of births but of people: 883 women called Jacoba were living in Spain on 1 January 2025, of every age, born in any year. Where they live is not spread evenly.

Listed in 39 of Spain's 52 provinces. In the other 13 it is either held by fewer than 5 people – the point below which the source withholds a name – or it fell past the 5,000 names the source will print for one province. Neither means nobody there is called it. The rate is the source's own, not a share worked out here.

Source: US Social Security Administration, national and state baby-name files, 1880–2025. Counts include only births registered with the SSA, and names with fewer than five births in a year are not published. The living estimate applies SSA cohort life tables to those births; it counts people born in the United States, so it misses anyone who arrived later and anyone who has left.
