In the present study, we analyzed the "vocabulary checklist" of 310 children aged 12-23 months. We focused on the relationship between age and the size of the noun vocabulary that children have acquired, what word category is acquired earliest, and the relationship between the sequence of vocabulary acquisition and age. The results showed that (1) the proportion of nouns was comparatively high in the vocabularies of all children, (2) the number of nouns that have been acquired increases with age, and (3) the word category that is closely related to the daily life of a child and expresses "things", such as "animals", "people", and "food and drink", is used most frequently. These results indicate that environmental factors influence vocabulary acquisition. Therefore, it is necessary to statistically examine the use of baby talk. Moreover, in addition to the expression of vocabulary, it is also necessary to examine the understanding of vocabulary.
