Show how many patients have a birth_date with 2010 as the birth year.

I'm sorry, but you didn't provide a specific question or dataset for me to work with. However, I can guide you on how to do this if you have a dataset in a format like CSV or if you're using a database.

If you're using a programming language like Python with a library like pandas, you can do something like this:

import pandas as pd

# Load your data
df = pd.read_csv('your_file.csv')

# Convert the birth_date column to datetime
df['birth_date'] = pd.to_datetime(df['birth_date'])

# Extract the year from each date
df['birth_year'] = df['birth_date'].dt.year

# Count the number of patients with 2010 as the birth year
num_patients = df[df['birth_year'] == 2010].shape[0]

print(f'There are {num_patients} patients born in 2010.')

If you're using SQL, you can do something like this:

SELECT COUNT(*) 
FROM patients 
WHERE EXTRACT(YEAR FROM birth_date) = 2010;

Please replace 'your_file.csv' and 'patients' with your actual file name or database table, and 'birth_date' with your actual date of birth column name.
