Data access and analysis of baby names statistics
Project description
babe
Note that the first time you import name, you need to have access to the Internet, and it will take a few seconds (depending on bandwidth) to download the required data.
But this data is automatically saved in a local file so things are faster the next time around.
To install:
pip install babe
Then in a python console or notebook...
from babe import UsNames
d = UsNames()
Intro to the data
The fundamental data provides a popularity score (number of babies recorded) associated to a (state, gender, name, year)
tuple (that has data -- for names of babies born in the US between 1910 and 2019).
d.data
state | gender | year | name | popularity | name_g | |
---|---|---|---|---|---|---|
0 | AK | F | 1910 | Mary | 14 | Mary_F |
1 | AK | F | 1910 | Annie | 12 | Annie_F |
2 | AK | F | 1910 | Anna | 10 | Anna_F |
3 | AK | F | 1910 | Margaret | 8 | Margaret_F |
4 | AK | F | 1910 | Helen | 7 | Helen_F |

6122890 rows × 6 columns
print(f"{len(d.names)} unique names")
31862 unique names
But some names can be used for both genders, so most of the internals will use name_g
, the name concatenated with the gender (_F
or _M
):
print(f"{len(d.name_gs)} unique names_g (gendered names)")
34952 unique names_g (gendered names)
You can use resolve_name_g
to get the name_g
corresponding to a name as long as the name isn't used for more than one gender.
d.resolve_name_g('Cora')
'Cora_F'
try:
d.resolve_name_g('Vanessa')
except AssertionError as e:
print(e)
The Vanessa can be used for both genders. Specify Vanessa_F or Vanessa_M
by_state data
In some cases, it's more convenient to have a view indexed by (state, name_g, year)
.
The by_state
attribute provides that.

This allows one to do things like getting the data for a given state only:
d.by_state['CA']
name_g year
Mary_F 1910 295
Helen_F 1910 239
Dorothy_F 1910 220

... within a state, getting the 'by year popularity' for a given name:
d.by_state['CA']['Cora_F'] # or d.by_state['CA', 'Cora_F']

... if you wanted to get the data for a given name (really name_g
), for all states, you can do it using "slicing".
For example, if you're wondering how many little boys were called "Vanessa", and more specifically, when and where?...

Misc
gender-ambiguous names
We'll call the "femininity" of a name be the proportion of times it was used (all states, all time) to name a girl, and the "masculinity" of a name be defined accordingly.

The (gender-)"ambiguity" of a name can thus be defined as twice the minimum of it's femininity and masculinity.
By defining the ambiguity thusly, we have a score that is between 0 and 1. It is maximal (1) when an equal proportion of boys and girls were named with the name. It is minimal (0) when only one gender was named with it.
Note that this score is raw (or "un-smoothed"). It's computed with the raw counts, so the extreme scores will usually be for names with very low counts.
