Final answer:
In the 1950s and 1960s, there was continued growth in the number of converts, new churches, and ordinations, with evangelical Christian denominations experiencing a significant increase.
Step-by-step explanation:
The growth rate of converts, new churches, and ordinations in the 1950s and 1960s can be described as follows: there was continued growth in all three areas, with certain segments experiencing particularly significant increases. Evangelical Christian denominations saw a tremendous surge in membership, with denominations such as Southern Baptists becoming the largest in the nation, and other denominations such as the Church of Jesus Christ of Latter-Day Saints, Seventh-Day Adventists, and the Assembly of God also experiencing tremendous growth and influence. The distribution of denominations across the United States points to various growth trends, ethnically and geographically diverse, with certain areas seeing increases due to factors like ethnic majority preferences, chain migration, and historical population developments after events such as emancipation.
