Final answer:
The incidence of bipolar I disorder in the general population is estimated to be approximately 1-2%.
Step-by-step explanation:
The incidence of bipolar I disorder in the general population is estimated to be approximately 1-2%.
According to a study published in the Archives of General Psychiatry, the average percentage affected by bipolar spectrum disorder in the World Mental Health Survey Initiative was found to be around 1-2%.
This indicates that a small portion of the general population experiences bipolar I disorder.
It's important to note that the incidence rate may vary across different countries and populations, but based on available research, the estimated range of 1-2% is the most commonly accepted figure.
