The geographical dynamics of talent migration in the US are constantly evolving. In the 2020-2021 period, several metropolitan statistical areas (MSAs) have seen a net positive migration of tech talent. Dallas recorded a 0.25% increase, Austin saw a 0.5% increase, and Miami experienced a 2.0% increase. On the other hand, MSAs such as Los Angeles, Chicago, and San Francisco saw a net negative migration of tech talent, with decreases of 0.75%, 0.75%, and 1.5%, respectively. 

The pandemic has played a significant role in changing the population dynamics in the US. Remote work opportunities have led to a migration of tech talent to states such as Florida, Texas, and Arizona. In contrast, states like New York, California, and Illinois have seen a high net outbound migration of tech talent. 

Traditional tech hubs like San Francisco, New York City, and Boston have been the biggest losers in terms of talent migration. The adoption of remote work has accelerated the move of tech talent away from these areas. Dallas, Austin, and Denver have emerged as the biggest talent gainers, with recruiters now having to consider this talent flux when hiring new talent. 

Several factors are driving tech migration in the US. The increased remote opportunities and attractive taxation regimes in certain states have played a significant role. Sustainable living conditions and improved tech infrastructure in smaller cities have also contributed to the migration of tech talent. It is essential for recruiters to keep track of these trends and adapt their hiring strategies accordingly.
